Great Highlight! Fun to run through. After a rainy period, be prepared to use your flashlight to avoid puddles.

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)

Haunted tunnel. Probably a silent witness to the old mine

Directly behind the church you will find this very large Mariengrotte. I am always amazed at the way the French pay homage to Mary
