The Sanctuary of Isis and the Magna Mater was a sanctuary in Mainz, dedicated to Isis and Magna Mater.[1]
The temple was founded during the 1st century and remained active until at least the 3rd century. Its remains were discovered in late 1999, during construction of a shopping arcade (later named "Römerpassage") in the city centre. Substantial excavations have been made at the site since.[2] The remains of the building, selected finds, and a multimedia framework presentation can be viewed in a small museum in the basement of the Römerpassage. Consecration inscriptions suggest that the Flavian imperial house may have been involved in the foundation of the sanctuary.
