The mountain saw at the old Maria Theresia Berghaus on the Ischler Salzberg: A saw was of great importance for every salt mine operation, since the mine operation required large quantities of "Ladwerk" (thick boards) for the expansion and the brine production. Therefore there was at least one, but usually several saws at each salt mine, which is why they were also among the oldest systems of the respective salt mine. Three saws are known on the Salzberg in Ischl: as the oldest, the Steinberg saw with the "Schafferklause", the Grabenbach - or Graben - saw built near the Ludovika tunnel and a third, from 1867, at the old Maria Theresia Berghaus. The following report will mainly deal with the latter saw, also known as the mountain saw, since the other saws and the associated Klaus systems were already dealt with in detail in the 2012 article by Franz Federspiel "News from the old Ischler Salzberg". Situation of the mountain saws on the Ischler Salzberg in the 18th century: Originally there were two plank saws on the Ischler Salzberg, the one on the Steinberg and the Graben saw below the Ludovika tunnel. The Steinberg saw was probably built immediately after 1563 with the start of salt mining in the Steinberg district. According to a note in Dicklberger's "Salinen - Geschichte" (volume 1, p. 388), the Steinberg saw existed before 1586. Figure 1: Steinberg - saw, conversion plan, 1842, archive Salinen Austria Figure 2: Steinberg - saw, ground plan, conversion plan, around 1845, archive Salinen Austria Due to the concentration of salt mining on the Pernecker salt storage and the associated deepening of the mining tunnels, the ditch - saw at the Ludovika - Berghaus was built. The exact date of construction of this saw, which was probably built around 1700, could not be found in the files. The first known documentary reference from September 25, 1769 provides information that the ditch saw and the associated hermitage were rebuilt after a fire at the estimated cost of 292 fl 52 kr. In the course of the conversion, a new storage hut was built along the entire length of the hermitage to store the saw cuts. The Graben - saw along with the associated hermitage had completely decayed again in 1816 and was rebuilt in the three following years. In 1839 the woodwork of the hermitage was rotten again, and the water wheel and the river also needed replacing. Figure 3: Ludovika Berghaus, site plan with ditch – saw, 1839, Archiv Salinen Austria Because of the high repair costs to be expected, in 1839 the Ischl mining operations manager at the time, Franz v. Schwind to leave the Graben saw at all and instead expand the Steinberg saw to make it more efficient. When converting the Steinberg saw, Schwind succeeded in increasing sawn timber production fourfold compared to the previous ones by using an overshot water wheel and a belt transmission in the gearbox, the first saw drive of this type in the monarchy. As a result, the sawn timber requirement of the entire Ischler Salzberg could be satisfied by the sole operation of the Steinberg saw. Figure 4: Steinberg - saw, design of an overshot water wheel, 1840, archive Salinen Austria The operation of the ditch saw should only have continued on a smaller scale, since the cost of bringing the cut goods from the Steinberg saw to the Pernecker tunnels via a specially created goods route was very expensive. For this purpose, Schwind replaced the desolate Grabenbach hermitage with a wooden weir in 1839. After the Graben saw burned down again in 1856, it was finally abandoned.

After the final closure of the Grabenbach saw in 1856, the entire sawn timber requirement had to be laboriously transported from the Steinberg saw down into the valley. For this reason, the plan was made around 1865 to move the Steinberg saw closer to the Pernecker tunnels. Various installation sites were tested: at the Grabenbach at the confluence of the Gaisbach opposite the Josef tunnel and directly at the Sulzbach or, connected to the Sulzbach via a river, at the old Maria Theresia Berghaus. Figure 8: Project transfer Steinberg - saw to the Josef tunnel, around 1865, archive Salinen Austria In view of the focus of the advance in the Empress Maria Theresia tunnel and the short transport routes, the decision was made to transfer the saw to the old Maria Theresia Berghaus. The transfer of the Steinberg saw to the new location took place in 1867. By using the old saw drive and parts of the old saw building, the costs were kept low at a total of 669 fl 81½ kr. Figure 9: Transfer Steinberg - saw to the old Maria Theresia Berghaus, 1865, Archiv Salinen Austria Figure 10: Transfer Steinberg - saw to the old Maria Theresia Berghaus, 1865, Archiv Salinen Austria Figure 11: Transfer Steinberg - saw to the old Maria Theresia Berghaus, 1866, Archiv Salinen Austria Description of the gear mechanism of the plank saw: With the report prepared by Franz Kreuzhuber, manipulation pupil Ite class, on March 14, 1868, there is a precise, contemporary description of the historical saw drive: "Where there is great hydroelectric power, undershot water wheels of 2 to 3 feet in diameter and 5 to 6 feet wide are usually used to operate the board saws. Here an overshot water wheel with a diameter of 12 feet and transmission is put into operation. A cog wheel of 6 feet diameter fastened to the base of the water wheel sets a driving wheel and with it a pulley of 6 feet diameter, - this by means of belts a second pulley of 1 ½ feet diameter, with it a wooden flywheel of 6 feet diameter and at the same time an iron winch in motion, whose arm carries a rod connected to the sag container /: Saggatern :/ in its circumference, which pushes the same up and down in a vertical guide. The Saggatern is assembled from 4 pieces of wood in the form of a door frame, to the short pieces of which the Sagblatt is screwed. Since the saw always makes its movement in the same place, a device is necessary for advancing the object to be cut in proportion to the power of the saw. This device /: Sagwagen :/ is a twenty-seven foot long frame movable on a horizontal slide and fitted with small rollers for ease of movement. To move it forward, the sagger carries a 7-foot-long horizontal rod on the lower crossbar, the end of which is fastened in a shaft Rings with indentations /: Thrust ring :/ gives an impact to the surrounding wheel of 3 ½ feet in diameter and as a result rotates the same slowly. During the retraction of the former, a second bar holds the thrust ring against slippage. The wheel, which is attached to the iron base of the thrust ring and is similar to the drive wheel, pushes the sag wagon through the combs attached to it along the entire length according to the power of the saw. A second overshot water wheel, 6 feet in diameter, is used to move the sag wagon backwards to its previous position, the shaft of which winds around a rope which runs over a small pulley attached to the end of the track and is attached to the sag wagon. As the sag wagon moves forward, it unwinds the rope from the shaft again.” In the following plan, the original work of the Steinberg saw is shown as it is described in the report by Franz Kreuzhuber in 1868 during the transfer. Only the second, smaller water wheel for moving the sag wagon backwards was added at the new location at the old Maria Theresia Berghaus. Figure 12: Gear mechanism of the Steinberg saw, 1857, archive Salinen Austria Saw - Fluder: After the transfer, the service water for the saw was no longer fed through a hermitage, but through a small cushion in the Sulzbach. The "Schmiedenfluder" from the Sulzbach, which has existed since about 1825, could be used for this purpose. This river had to be built for the operation of the mountain forge, since from 1825 larger amounts of water were diverted from the Grabenbach via the water scour into the Elisabeth tunnel in order to be able to provide the service water required for the Laistauss flooding in the Maria Theresia tunnel. The amount of residual water in the Grabenbach was often too low for the operation of the forge at the Maria Theresia tunnel. The river was designed as an open wooden channel made from cut posts, 72 m long and 0.6 m wide. As early as 1881, the river, which had been renewed in 1867, had to be removed due to damage and a new river channel including water catch and wheel hut had to be installed at a cost of 719 fl 81 kr. to be erected. Further repairs of this kind on the fluder were necessary in 1891, 1905 and 1933. Figure 13: Saw - fluder, 1904, archive Salinen Austria Performance of the two saw - water wheels: The overshot water wheel for driving the gang saw had a diameter of 3.7 m and a width of 1.0 m, depending on the water pressure, an output of 4 - 5 hp; the also overshot water wheel ("mold wheel") for reversing the saw carriage with 1.7 m diameter and 0.75 m width 1 - 2 HP. Figure 14: Saw - water wheels, 1866, Archiv Salinen Austria Figure 15: Mountain saw with old Maria Theresia mountain house, around 1930, Kranabitl archive Figure 16: Mountain saw at the old Maria Theresia Berghaus (upper left edge of the picture), around 1930, Archiv Salinen Austria Modification of the mountain saw's gearbox: In 1879, a circular saw was installed in the firewood store next to the mountain saw to cut the firewood better. This circular saw could be operated directly from the saw by means of a transmission transmission. In 1893 the gearbox of the mountain saw had to be repaired because it was defective. The complex maintenance of the saw fluder and the water wheels as well as the low performance of the mountain saw caused the management to convert this saw to electric operation in 1950. For this purpose, a stationary electric motor with 750 rpm was installed. From the 325mm diameter drive wheel of the electric motor, a belt led to a 1550mm diameter pulley on the main shaft. A second belt drive was placed on the main shaft on the stream side, which connected a belt wheel with a diameter of 900 mm on the main shaft to a belt wheel with a diameter of 730 mm on the water wheel shaft to move the saw gate. Another belt drive on the uphill side enabled the forward and backward movement of the saw carriage by means of a chain. Figure 17: Conversion of the plank saw to electric operation, 1951, Archiv Salinen Austria In the course of the electrification of the saw drive, a side saw was also installed. For this purpose, the sawing building had to be structurally extended.

Since the migration of the mining industry from Perneck to the new site at the Kaiser Franz Josef Erbstollen in Lauffen in 1989, the saw building has been empty.

The historic sawmill is well-preserved and, as a unique technical monument that is otherwise rarely found in the Salzkammergut, is particularly worthy of protection. The main elements of the saw gear, which dates back to 1847 and is made of wooden gears, have been preserved to this day. In 2021, with the support of Salinen Immobilien AG, IGM would like to secure the building fabric, set up a showroom in the area of the former sawmill and have the technical history of the saw documented as part of diploma theses.

12 The John tunnel Stud Name: "St. John of Nepomuk - Stollen" originally watering scree, named after "water saints" Struck: 1725 Leave: 1831 Length: 230 m Altitude: 991 m In 1725, the St. Johannes tunnel was struck to bring in the still unleached mountain thickness of 10 Stabel (11.9m) between the Matthias and Obernberg tunnels and to leach existing works above the level of the Matthias tunnel. Initially, this building was only intended to serve as ventilation and drainage for the princes' weir. However, when the salt was reached during the excavation of this Ebenschurf in 1730 and the cleansing pit was connected to the princes' weir by sinking, the still unnamed building was given the name St. John of Nepomuk tunnels. The St Johannes tunnel – main shaft was driven entirely in the squeezing clay rock. The tunnel timbering lasted barely 1 year. Therefore, 2 scaffolds were constantly needed to keep the tunnel open to traffic. Situation of the weirs in the St. Johannes tunnel around 1800: Length from the mouth hole to the salt boundary 219 bars (261.7 m), from there to the field site 190 bars (227.1 m). 2 hairpin bends with a total of 3 weirs, 2 of which are unusable (Fürsten - and Wimmer - Weir) and 1 usable (Zierler - Weir). Because of the rich salt mountains, the decision was made to extend the prince's weir beyond the Matthias tunnel. For this purpose, a cleaning pit, a sink works and 2 dam outlets were built from the St. Johannes tunnel. In 1733 the prince's weir could be watered again in order to be able to use the thickness of the mountain down to the St. Johannes tunnel. In 1744 the prince's weir went down because it was too close to the overlying rock and fresh water had broken in. The princes' weir now had to be dammed up and abandoned. The Kain and Tratl weir in the Matthias tunnel, which had been in operation since 1648, was also to be leached beyond the Matthias tunnel. Since the Kain and Tratl weir had already fallen into disrepair, a sinkage was sunk from the St. Johannes tunnel in 1738. In doing so, devious brine was encountered. In 1764, a second sinkage, located further towards the day, was sunk from the St. Johannes adit - main shaft against the Kain and Tratl weir. After the construction of 2 dams, the facility, now known as the Zierler weir, could be watered again and watered higher towards the St. Johannes tunnel. In 1802 there was an unexpected decline in the factory, which relocated the two drain boxes of the Zierler weir. The drain boxes could be found under the companionway and prepared. In 1807 the factory went down again. The Zierler weir, which had been emptied down to 17 rooms (1,924m³), could no longer be emptied any further. In 1 week, only ½ room (57m³) of brine drained away, then the drain dried up completely. Since the old sinkage also became completely unusable due to the decline, a new sinkage had to be sunk, and through this, the brine still in the weir had to be laboriously pumped up. The Wimmer weir was built in the eastern part of the St. Johannes tunnel to use the salt agents that remained behind the Zierler weir. However, since there was a risk when the Wimmer weir was flooded that the surface water in the Lipplesgraben tunnel could break through and the salt mountains were very poor, it was completely abandoned again in 1781. Around 1800, the weirs in the Johannes tunnel were largely exhausted. Despite the rich salt deposits that were still available in places, these could not be used further because they were too close to the surface and there was a risk of fresh water ingress. The remaining mountain forts were necessary to support the mountains and were not allowed to be weakened under any circumstances. The tunnel hut near the St. Johannes tunnel burned down completely in 1787. Situation of the weirs in the St. Johannes tunnel around 1850: A total of 3 weirs, all pronounced dead around 1850; Wimmer - weir, Zierler - weir, princes - weir. Until 1933, the drainage path led in the St. Johannes tunnel from the water intake point on the Sulzbach via the drainage pit to the main shaft and on to the Saherböck pit, over which the water flowed down into the Matthias tunnel. The rear part of the St. Johannes tunnel was finally abandoned.

13 The Emperor Matthias – tunnels + iron ore Stud Name: "Archduke Matthias - Stollen", from 1612 "Kaiser Matthias - Stollen" Emperor Matthias, reign 1612 – 1619, son of Emperor Maximilian II. Struck: 1577 Length: 420 m Altitude: 959 m In 1577, after looking around for 14 years and still not finding anything special, the mining experts of the Salzamt decided to convert a trial dig from the Neuhauser - Kehr im Obernberg - tunnel into a weir and to dig a new mountain below to drain the brine . It was the Archduke Matthias tunnel that, after nine years of driving through limestone, finally came across salted Haselgebirge. As expected, the Matthias tunnel - main shaft soon reached the rear, eastern salt boundary again. However, a trial transverse building opened up good Haselgebirge over a longer distance. Two mountain inspections were carried out in 1584 for a more expedient opening up of the Ischler Salzberg. In the Archduke Mathias tunnel, because the salt mountains had improved, a new building was to be built behind the so-called water building. In the meantime, in the Matthias tunnel, the main shaft and two test digs had been driven out of the salt into the water-bearing limestone. In 1586 a mountain inspection was carried out again at the Ischler Salzberg. It turned out that the test pit sunk by the Archduke Mathias tunnel had encountered good salt rock over a whole mountain thickness. For this reason, the uncertain investigation work in the mining tunnels at Obereck ("Moosegg") and Roßmoos should be stopped quickly and the Archduke Matthias tunnel should be driven under with a new hill climb, the Neuberg tunnel. Situation of the water dams and weirs in the Kaiser Matthias tunnel around 1654: A total of 9 waterworks; Water, Archduke Matthias, Seeauer, Rettenbacher, Hippelsroider, Cain, Our Lady, Haimb and Klein Trattel – building. The 9 Schöpfbaue were already cut before 1648 and were used as princes - as well as Kain and Trattel - weir with indulgences in the Frauenholz - tunnels. The Matthias tunnel – main shaft was 387 stalks (461.3 m) long until it reached the salt boundary. 6 Stabel (7.2m) after the salt line there was a test dig down into the Neuberg tunnel. On the continuation of the Matthias tunnel - main shaft 9 constructions were created. Namely the water - and Archduke Matthias - building, which lay under a sky and contained 42 rooms (4,754m³) brine. The two constructions were undercut from the Neuberg tunnel with a weir furnace and referred to as the prince's weir. In 1725 the base of the Fürsten weir in the Matthias tunnel broke through into the Rassfellner weir in the Neuberg tunnel below. The princes' weir was later extended up to the St. John's tunnel and only abandoned around 1744. The following buildings, namely the Seeauer, Rettenbacher, Hippelsroider, Kain, Fraun, Haimb and Klein Trattel buildings contained 60 rooms (6,792m³) of brine and were also under a sky. They were also run under from the Neuberg tunnel with a weir furnace and prepared for an outlet weir. This weir was called the Cain and Trattel weir during the leaching in the Matthias tunnel. When it was further watered down into the St. Johannes tunnel, it was renamed the Zierler weir. The Zierler weir was in operation until 1807. Behind these buildings, the Matthias tunnel - main shaft was still 16 Stabel (19.1m) long. Their field place was already in the deaf mountains. In 1654 the thickness of the mountain from the Matthias tunnel to the Obernberg tunnel was still around 10 bar (11.9m). The St. Johannes tunnel was opened in 1725 to gain this mountain thickness and for higher drainage of the weirs created in the Archduke Matthias tunnel. In 1656 there was a partly brick and partly wooden mountain house near the Matthias tunnel. When this was later removed, the still usable woodwork was used to build a, not far from the Neuberg - tunnel built under the name Taxhaus, wooden room. Miners were housed in this wooden room. The Starhembergsche inspection commission of 1707 already found the Matthias tunnel devious, behind the dam outlet there were collapsed weirs, which were exploited by robbery watering, whereby the generated brine flowed through the main shaft. The introduction of the fresh water required for the leaching in the deeper tunnels came from the stream and the springs in the area of the Matthias tunnel mouth hole. The water collected in wooden tubes was fed into the mountain via the Matthias tunnel – main shaft. From 1769, the water needed to dilute the weirs was channeled through a surface dig above the St. Johannes tunnel and from there via the Saherböck dig to the Matthias tunnel main shaft. From 1784, the water required for brine production was collected in a “watering hut” above the Matthias tunnel and diverted via the newly built watering pit to the Matthias tunnel – main shaft. From there, the water reached, depending on the need, either through the pastor Weissbacher - Schurf and the subsequent digging to the weirs located on the evening side (west side) in the deeper tunnels. The morning (eastern) weirs could be over the v. Adlersberg - conversion and the Weilenböcker - digging and the subsequent digging can be achieved. Situation of the weirs in the Matthias tunnel around 1850: A total of 3 weirs, all pronounced dead around 1850; Preuner and Raßfellner weir, from Frauenholz - via Neuberg - up to Matthias - tunnel. Zierler – weir and princes – weir from Matthias – on St. Johannes - tunnel up verlaugt. Until 1933, the drainage route led in the Matthias tunnel via the drainage pit to the main shaft and along this further to the Plenzner pit leading down into the Neuberg pit. In addition, another water pipe came down from the St. Johannes tunnel via the Saherböck scour to the main shaft. In 1931, during the main inspection, it was decided to leave the Matthias tunnel open because future watering should come from the Törlbach via the Maria Theresia tunnel. For this reason, dams were built in 1932 at the end of the tunnel and at the head of the Plenzner and Weissbacher quarry. A final inspection to check the dams took place on February 5, 1934. The tunnel entrances to the Matthias tunnel and the drainage pit were then finally sealed.

From there, the water reached, depending on the need, either through the Pastor Weissbacher - digging and the subsequent digging to the on the Evening side (west side) located weirs in the deeper tunnels. The morning (eastern) Defense could over the v. Adlersberg – conversion and the Weilenböcker – Schurf as well the following prospects can be reached. Miner Franz v. Schwind started in 1842 Laying of cast-iron water pipes at the Ischler Salzberg. This made it possible the long way that those in the upper horizons collected water had to travel to fill the leach workers, since the iron pipes could be under higher pressure than the wooden pipes. The rapid supply of larger amounts of water to the production workers and drainage the stretches soaked by the weeping wooden pipes was now possible. In September 2018, members of the IGM uncovered the mouth of the drainage pit, revealing a surprisingly well-preserved portal. Text: Archive Salinen Austria, Archive IGM Water basin for watering into the Matthias tunnel Built 1883 - In service until 1934 In 1883, to secure the machine and watering operation in arid times the manufacture of a large concrete water collection trough in the near the Matthias – Stollen in place of the one that has existed for ages rotten collection box made of wood approved. This one covered with a simple wooden hut water collection trough, served for feeding the winding machine and for the leaching operation. In September 2018, members of the IGM approx. 100 m3 capacity Water basin at the Matthias gallery cleared of trees at the edge of the basin, which on the one hand restricted the view of this building, on the other hand threatened to burst through the concrete wall with their roots. This water basin is fed by the very productive "Kaltenbrunn spring". This basin is the largest surviving building which was built from "Pernecker Romanzement" - hydraulic Pernecker lime, also known as "Hydrauer". This was produced in large quantities in the cement works at the Josefstollen.

However, for the most part it has remained at prospecting attempts and only in a few cases has there been short-term mining. The ore deposits are exclusively sulphide ores such as pyrites, galena, chalcopyrite and sphalerite, which are accompanied by spar iron and brown iron ore and occur on the border between Werfen slate and dolomite. On the Reinfalzalm above the Ischler Salzberg, iron mining in the so-called "Eisenarz" can be traced back to the 15th century. Around 1500, a certain Hans Gaisbrucker from Lauffen operated a mine for pyrite and brown iron ore including a vitriol smelter. The remains of 4 tunnel mouths from iron mining can still be found in the area. The iron smelter was probably at the foot of the Salzberg just below the mouth of the Leopold tunnel. This is confirmed by slag residues that can be found in the ground in the area of the lower barn that was removed, the former impact room and up to the Auer well. Vitriol was produced by roasting the pyrite, extracting the iron sulphide, which had been subject to a weathering process for several months, with water and boiling the solution until the blue-green vitriol crystals crystallized out. For this roasting and boiling process, 100 Rachel wood, which is around 700 m³, were used annually. The Vitriolsudhütte was not far from the Matthias tunnel at the foot of the Sudhüttenwand. The 100 m³ heap can still be seen here today. The by-products of vitriol boiling are a strongly red-colored, earthy mass that was used as red chalk by masons and carpenters. Dicklberger (1820) writes about the fate of the vitriol works at Reinfalz: When in 1562 the exploration of the Ischler Salzberg was suggested by Hans Praunfalk, administrator in Aussee, the high directive was issued at the same time "to occupy the Salzberg, to visit the salt store, to diligently tend the forests on the Reinfalz, Mitterberg and in this area, and to completely stop all melting and boiling of the vitriol in these places in order not to tolerate any waste in the forests that will be necessary in the future for salt brewing.” Emperor Ferdinand I gave this order on September 25, 1562 and one year later the Ischl salt mine was approached. This sealed the fate of the vitriol boiling plant. In the 1920s, two of the tunnels used to access the ore deposits were rediscovered by the Perneck miner Josef Hütter. According to old miners, the upper Eisenarz tunnel had been retrofitted in 1866 by the then mine manager August Aigner on his own initiative. The lower left iron ore tunnel was reconstructed 12 m by a group of speleologists from Linz at the end of the 1930s. In 2014, under the direction of Horst Feichtinger, a 7 m long new tunnel section was cleared in the mouth hole area of the upper iron ore tunnel. In 1858 the same ore formation had been driven through when the tamper turned in the Maria Theresia horizon. The vertical distance between the Eisenarz and the Stampfer - Kehr is around 400 m. 2. Location and geology: The Eisenarze area is some 100 meters south of the Reinfalzalm (1026 m) on the Ischler Salzberg. Here, at the northern foot of the Sudhüttenwand, a ditch runs steeply in the forest in a SE direction. This graben is of tectonic origin and forms the boundary between limestone (Jurassic) in the NE and dolomite (Triassic) in the SW. The ditch extends to the crest of the ridge formed by the Sudhüttenwand and the Zwerchwand at about 1170 m above sea level. Of the tunnels from the 16th century in the area of the ditch, only the upper iron ore tunnel, also known as the "Hütter-Stollen" after its rediscoverer (1920), is still conditionally passable today. From the other 3 you will only find Pingen and Halden, from the bottom left Iron ore tunnel even still has the mouth hole. Above the Hütter tunnel, the mineralization is exposed on a cuirass. Otherwise there are no more outcrops during the day. The mineralization can be found at the layer boundary between the Werfen slate and the Hallstatt dolomite. Sulphide ores include galena, sphalerite and pyrites. Calcite, dolomite and siderite (iron carbonate) form the carbonates and brown iron ore and quartz form the oxides. Dolomite occupies the largest space in the ore pieces that can be found, calcite and siderite are rare. As a typical weathering mineral, brown iron stone is only found near the surface. The most conspicuous and predominant sulphide mineral is galena, which can be found up to 8 mm thick veins that are easily visible to the naked eye. Zinc blende can only be detected microscopically. You won't find pyrites at all. However, the existing vitriol boiler requires a pyrite deposit. 3. Cleats: 3.1. Lower Left Iron Ore Adit: The lower left iron ore adit is at an altitude of 1018 m and is easy to find, as the damp and cold weather rising from the mouth of the adit forms a vapor strip that is visible from afar. Its entrance is frozen almost all year round. The tunnel was rebuilt at the end of the 1930s to a length of 12 m. Following that, he's been on the run since about 1985. The tunnel was originally passable over a length of about 30 m. Near its aft end was a shaft that had completely collapsed at a depth of about 15 m. The entire tunnel including the shaft is in Jura limestone and there were no signs underground that it had ever hit another rock formation. The tailings pile consists largely of the same rock, but isolated pieces of Werfen slate can also be found. Since no mineralized rock is found, it can be concluded that the adit did not reach the mineralization at all. 3.2. Lower Right Iron Ore Adit: The lower right vitriol tunnel, previously unknown in the specialist literature, was discovered during field inspections by F. Federspiel, H. Feichtinger and E. Ramsauer in the summer of 2016. This tunnel is about 70 m south-west of the lower left vitriol tunnel at an altitude of 1024 m. The extensive slag heap is a good 28 m long at the crown. It is made up of fine-grained heaps containing plenty of ore. The size of the heap indicates what is probably the most extensive mine workings in the entire area. From the foot of the heap, the ore path, which is still clearly visible in sections, leads to the former vitriol sud hut near the Matthias tunnel. 3.3. Medium Iron Ore - Adits: The middle iron ore tunnel is located at 1040 m above sea level in the lower part of the steeply rising ditch that begins in Eisenarz. Nothing remains of the tunnel mouth, but the Pinge and the heap are still clearly visible in the steeply sloping terrain. In addition to samples from the Hallstatt dolomite and the Werfen strata, numerous pieces with relatively rich galena mineralization can be found. This heap is the richest of the 4 tunnels. 3.4. Upper Iron Ore – Adit: The mouth of the upper Eisenerz - or Hütter - tunnel is at 1105 m above sea level and is very similar to a natural cave entrance. Only when you have crawled through the narrow entrance area do you come to a chamber-like extension, which still contains the remains of an old wooden structure. The ceiling height in the center of the hall is up to 3.5 m. On the side, a short tunnel leads past a rock pillar into a second chamber, which can also only be reached by crawling. The second working chamber runs parallel to the first chamber and is offset to the SE. A third mining area can be reached via a short, narrow gap. The approximately 4.5 m long and around 1.5 m high excavation chamber shows white sinter formations on the ceiling, which clearly stand out from the black rock coatings. The further continuation of the tunnel is likely to be closed by a breach. There are no longer any documents about the former extent of the tunnel. While the first and second chambers are in the dolomite, pinching between the dolomite and the Werfen slate can be seen in the third chamber. The 7.5 m long part of the tunnel, newly discovered by Horst Feichtinger in 2014, begins about 5 m behind the mouth hole area. With a width of 50 cm and a height of 90 cm, it runs in a straight line and evenly in the SE direction. Sintering and mineral efflorescence can be observed on the tunnel ceiling. There are numerous black chunks on the heap of this tunnel, which only turn out to be ore-bearing after they have been smashed. The manganese-rich, black coating is the result of centuries of weathering on the rock. The mineralization here also consists mainly of galena. 4. Vitriol - production and use: Vitriols are minerals that belong to the salts of sulfuric acid (sulphates). The white zinc vitriol, the green iron vitriol and the blue copper vitriol are the most important representatives of this mineral class. The term vitriol comes from Latin and is translated as "glass", based on the glass-like appearance of the crystals of vitriols. Vitriols occur as oxidation products of sulphide ores. They are obtained by capturing leachates containing vitriol or by leaching weathered, oxidized metal ores. Georgius Agricola describes the production of vitriol in his work "Of the 12 Books of Metallurgy" published in 1556. Sulfur pyrites were leached out with hot water, the vitriol precipitated out of the solution and the resulting vitriol sludge was heated in a boiling furnace to evaporate the residual moisture. Iron vitriol was primarily used to color leather, the so-called "blackening of leather". Iron vitriols were also used in fabric dyeing, for the production of dyes and ink, and as a disinfectant. The representatives of the medieval alchemists saw more than just minerals behind the vitriole. For the alchemists, vitriols were the outer philosopher's stone, with the help of which the transformation of seemingly worthless materials into precious metals such as gold and silver should be possible. Despite centuries of research, the alchemists did not succeed in producing gold and silver with the vitriols.

02 The Emperor Franzens – Stollen Stud Name: Until 1808 "Lower Kaiser Franz - Stollen", then "Kaiser Franz Stollen" Emperor Franz II./I. (son of Emperor Leopold II), reigned 1792 - 1835 Struck: May 1, 1794 - together with Emperor Leopold - tunnels Length: 884m - 1834 propulsion set Altitude: 588 m The Kaiser Franz tunnel was struck together with the Kaiser Leopold tunnel on May 1, 1794. Around 1800, the Kaiser Franz tunnel had only been extended to 65 bars (77.7m). In 1809 the Court Chamber considered building a mountain house for Emperor Franz -- Stollen, for which 4244 fl. building costs were estimated. In 1811, the Verwesamt bought the building and garden area of 300 square meters from the owner Balthasar Gratzer for 150 fl Rent of 10 fl. In 1813 the Bergmeister Dicklberger was the first to move into the beautiful "Unteres Berghaus". The administration was in no hurry to drive the Kaiser Franz tunnel. From 1818 to 1822, tunneling was stopped altogether because the crew was needed to secure squeezing sections, and from then until 1830 the tunnel only advanced by 7 rods (8.4 m) into the field. It was now 743 Stabel (884.0m) long and still needed 1187 Stabel (1418.5m) to reach the salt line. It didn't come to that, in 1834 the administration stopped the construction of the tunnel altogether, with the intention of re-occupying it only after the completion of the Kaiser Leopold tunnel. It was not until 70 years later that the Kaiser Franz tunnel was replaced by the 1st blind horizon, which had been driven through the Distler shaft in 1904. From 1966 the "Franzberg - Haus" was used as an administration building for the ammunition depot in Perneck of the Austrian Armed Forces. During this time, a shooting range was installed in the Kaiser Franz tunnel and the tunnel was walled off after about 100m. The "Franzberg House" is now privately owned and cannot be visited.

11 The Lipplesgraben – tunnel Stud Name: "Obernberg - Stollen", original name as a new hill climb above the Mitterberg tunnel in the Perneck salt storage facility. "Lipplesgraben - Stollen", later name as locality designation. Struck: 1567 Length: 236 m Altitude: 1,001 m In 1567, under Emperor Maximilian II, the "Alte Steinberg tunnel" in the Steinberg camp and the "Obernberg tunnel" in the Perneck camp were struck. The Lipplesgraben tunnel, located at 1,001m above sea level, was the highest horizon on the Ischler Salzberg that led to the salt storage. A mountain survey in 1575 found the field site of the Obernberg tunnel in the Tauben and a trial dig sunk from the back of the head, also in very poor mountains. Nevertheless, it was decided to drive the main shaft a further 110 stakes (119.5 m) in the hope that salt would be found again, albeit in vain. In the Obernberg tunnel, later known as the Lippelsgraben tunnel, the Pernecker salt deposit was discovered only by chance. Since the tunnel was started at the outcrop of the Pernecker camp below the Reinfalzalm, only the mostly depleted Haselgebirge could be approached. In 1577, after 14 years of searching and yet nothing special could be found, the mining experts of the Salzamt decided to only design the test dig from the Neuhauser - Kehr im Lipplesgraben - tunnel to a construction and to drain the brine below, a new one Stollen, the Matthias – Stollen, open. Situation of the pumping pits in the Oberberg tunnel - building around 1600: A total of 5 waterworks; on the Neuhauser – bend of the St. Florian – , the Rettenbacher – and an unnamed burrow; on the main shaft of the Spiller - burrow and an unnamed burrow. The main shaft of the Lipplesgraben tunnel first went 128 bars (152.6m) through solid limestone, then 45 bars (53.6m) through barren, exhausted rock to reach the salt limit, where the Neuhauser bend was extended to the right. On the Neuhauser turn there was an old probation pit that was built to investigate the depths of the salt mountains, then the St. Florian - and Rettenbacher - construction and another, unnamed construction. The field location of the 95-stabel (113.2m) long Neuhauser Kehr was in stone and since a stretch of 39-stabel (46.5m) had already fallen, freshwater penetrated there. On the continuation of the main shaft there was the main quarry down the Archduke Matthias tunnel, because of the poor salt mountain 77 Stabel (92.0m) inwards the Spiller construction and another, unnamed construction, which were later undercut by the Archduke Matthias tunnel and have been prepared for discharge weirs. There was also an old test pit and a lettue weir at the site of the main shaft to prevent the inflow of fresh water. The length of the Lipplesgraben tunnel - main shaft from the mouth hole to the field site was initially 424 4/8 Stabel (506.0m); but since 199 ½ poles (237.8 m) had fallen back from the field site, 225 poles (268.2 m) were still open. The two burrows on the main shaft collapsed as well. There were also 4 trenches in the Lipplesgraben tunnel, namely three on the main shaft and one on the Neuhauser bend, namely the drainage trench from the "Lower Water Gallery", which was referred to as the "main treasurer Tusch - Schurf". In addition, there was a test dig from the main shaft and from the Neuhauser - Kehr to explore the salt mountains down to the Archduke Matthias - tunnel. In order to introduce the fresh water required for watering, the "Nieder Wasserstollen" was installed above the Lipplesgraben tunnel at 1,024m above sea level on the Rainfalz. The Nieder Wasserstollen was driven 75 Stabel (89.4m) long in the Tauben Mountains and was connected via a 31 Stabel (37.0m) long watering pit with the Neuhauser - Kehr located in the Lipplesgraben - adit. The fresh water was collected from a spring located above the drainage pit during the day and brought to this pit through vertical wooden pipes. Around 1654 the Lipplesgraben tunnel was almost completely drained. From this time on, the tunnel was only kept open to drain fresh water so that it could not cause any damage to the tunnels below. In 1739 the "middle water gallery" with lateral openings at the Rainfalz and the extension of the drainage system between the mountains were built. Although some water was built with this new tunnel, the hoped-for success was not achieved because the fresh water was still penetrating the Streubel and Seutzen weir in the Frauenholz tunnel. It was not until 1769 that the access to the water was successfully contained by the water digging in the Lipplesgraben tunnel. In 1769 Hofkammerrat Gigant found the surface water that had penetrated into the Frauenholz tunnel well summarized in the Lipplesgraben tunnel. To protect the salt storage against the sedimentation of rainwater, the daytime area at Rainfalz and between the mountains was criss-crossed by a dense network of drainage ditches and side channels, the constant good maintenance of which required great expense. In order to reduce this, the Verwesamt decided in 1795 to give up that part of the drainage system that ran over lettuce, i.e. water-impermeable ground, and where there was no fear of the ingress of surface water. Around 1820, the Lipplesgraben tunnel was kept open for ventilation and for the drainage of the fresh water that had been built in this tunnel by creating several water openings. Those connecting structures that had become superfluous after the drainage pipe was relocated in 1842 were left open. These included the "Niedere Wasserberg - Schachtricht" and the Wasserschurf (Niederer - water tunnel on Lipplesgraben - tunnel), the rear Lipplesgraben - and St. Johannes - tunnel, some stretches in Matthias - and Neuberg - tunnels as well as the Kößler - conversion in the Frauenholz - tunnel. In 1892, the Imperial and Royal Ministry of Finance approved the construction of a workers' accommodation hut made of stone masonry in place of the wooden hut that stood near the Lipplesgraben tunnel opened in 1567. The construction costs amounted to 934 fl 70 Kr. for the land plaque - insert no. 1023, KG Perneck, BP. No. 18 with a size of 32 m². Until 1950, the "Stone and wooden water channel on the Rainfalz and between the mountains" was repaired annually by the Ischl salt mine and the construction crew lived in the tunnel hut near the Lipplesgraben tunnel. On December 31, 1933, the Neuhauser - Kehr and the Wasseröffen in the Lipplesgraben tunnel were closed and shut down. Finally, on April 3, 1934, the proper sealing off of the abandoned Lipplesgraben tunnel was completed and approved in the course of a main inspection.
