Mithraeum at Ballplatz

The Mithraeum at Ballplatz was a Roman sanctuary in the area of what is now the inner city of Mainz. It was located in the zone between Ballplatz square and Hintere Präsenzgasse, in the vicinity of today's Weißliliengasse. Its existence is attested by architectural remains, small finds, and several votive monuments, including a large marble altar with a complete dedication to Mithras. The complex was discovered in 1976 during construction work but was destroyed in the course of continued building activities, without any systematic excavation or documentation having taken place. In scholarship, an unusually early foundation of the temple, already at the beginning of the last third of the 1st century, has been repeatedly argued for. The sanctuary is considered an important piece of evidence for the presence of the cult of Mithras in Roman Mogontiacum.
