A Roman Temple to Isis and Cybele Sits Beneath a Mainz Shopping Mall

Beneath the Römerpassage shopping mall in Mainz, Germany, an ancient Roman religious site has been preserved in place rather than removed during construction. The Isis-Heiligtum, or Isis Sanctuary, is now presented as a museum within the shopping center. The complex was dedicated to Isis and Cybele, the latter identified with Magna Mater, or the Great Mother, in the Roman world. Both goddesses were described in the source as foreign deities who attracted considerable attention across the Roman Empire. Visitors reach the remains below the mall and view the dual temple from transparent glass walkways along its edges. The museum also presents information about people who visited and worked at the sanctuary. Among the site’s more unusual discoveries are magical objects buried in its grounds. According to Atlas Obscura, these items were connected with attempts to curse or bless various people. The material does not establish who placed each object or explain the intended outcomes beyond those reported associations. The museum also includes presentations about Saturnalia, featuring a recorded voiceover and videos. The preserved temple is located within an approximately 10-minute walk of Mainz Hauptbahnhof, the city’s main train station. The result is an ancient sanctuary displayed in an unexpected modern setting: a Roman temple complex beneath a functioning shopping mall, with visitors able to look down onto its remains while moving through the contemporary building above.
