Mithraeum (Latin mithraeum, plural mithraeen) is the name given to the temples of the Mithras cult. Mithraeums were usually built underground or carved into rock. A relatively small cult room was sufficient for the Mithras communities, which had only one to two dozen members. The largest known mithraeum had space for 80 believers. In contrast to Christianity, where larger churches were built in larger communities, in Mithraism the number, not the volume, was increased. At the height of the Mithras cult in the 3rd century, there were supposedly 800 mithraeums in Rome alone. However, since the individual mithraeums were usually not in use for long, this high number says nothing about the number of followers. To date, the remains of over 1000 mithraeums have been archaeologically proven throughout the entire Roman Empire.

For me this is one of the sensations in Saarbrücken! The cave and the recesses created later are still in great condition. There is also a bench under a ledge. If only it weren't for the car noise (like it was 2,000 years ago). "In pre-Christian and Roman times, a Mithraic cult was practiced on the Halberg - by the Gallo-Romans who lived here or the Roman soldiers of the nearby garrison. For this purpose, they created a barrel-vaulted mithraeum in the sandstone on the western slope of the Halberg, which is known in older literature as the "Heidenkapelle " is called. After Christianization in the 6th century, the grotto was incorporated into Christian worship. This means that the Halberg is possibly the oldest Christian place of worship in the region. The remains of this site can still be admired here and are in a relatively well-preserved condition." https://de.wikipedia.org/wiki/Halberg_(Saarland)

With the closure of the Amelung and Steinbach shafts in 1932 during the global economic crisis, Von der Heydt's time as an independent mine ended. In 1951 the Amelung shafts were swamped and used as extending weather shafts for the Viktoria mine in Püttlingen until 1963. During the construction of the Ludwigsstollen, the composite tunnel between the Luisenthal and Jägerfreude mines, the Amelung shafts were used in 1963 for ventilation, cable transport and material transport.[1] After the mine was finally closed in 1965, the daytime facilities were largely demolished. The mining machine house at the Amelung I shaft, a magazine building from 1885/1886 and the colliery house at the Amelung II shaft, which was built as an administration building and building in the early 1950s when the mine was reactivated, have been preserved.[2] The station building, which was built around 1870, has also been preserved. The station was used for passenger traffic until October 1959; until the end of the 1990s the one in Von der

it established the connection to the Steinbachtal in the east. The Kirchheckschächte and the Steinbachschächte were built at the Burbach tunnel.[1] Between 1865 and 1869, rope conveying was also used in the Burbach tunnel; between 1873 and 1917 the coal was transported using a chain railway.[2] In 1885 the mine employed 2,777 miners; Over 700,000 tons of coal were mined.[3] Between 1884 and 1886, the Amelung I shaft (named after the mining captain Karl Gustav Amelung, 1818–1866) was sunk; This means that the Von der Heydt mine transitioned from tunnel construction to civil engineering very late.[4] A second production shaft followed in 1899, the Amelung II shaft. In the east of the mine field, the Neuhaus I weather shaft was built in 1901. From 1920, as a result of the Treaty of Versailles, the mine was under French administration. In the district of Rastpfuhl, another weather shaft, the Pasteur or South Shaft, was sunk in 1922.

The pit - named after the banker and Prussian trade and finance minister August Freiherr von der Heydt (1801-1874) - was built in 1850 and is classified as one of the so-called railway pits that the Prussian mining treasury built when the Saar region was opened up by the Saarbrücken Railway. In 1852 the mine received a railway connection to St. Johann-Saarbrücken. In the upper Burbachtal, the location of the mine, coal mining had been carried out since at least 1770. In 1850, the approximately 1.3 kilometer long Von Heydt tunnel leading to the northwest was struck. In this tunnel, horizontal cable conveyance was used for the first time in Europe in 1862; previously it had been supported with horses. The Lampennest tunnel, which was started in 1853, served to promote the Lampennest mine, located north of the Burbachtal near Güchenbach (today Riegelsberg). Between 1855 and 1862, the approximately 2.3 kilometer long Burbach tunnel was excavated in the opposite direction.

Very great acting. I was there at minus 1 degrees. Then you can actually see the smoke. Unfortunately, you can't see it in warmer temperatures.
