Sanctuary of Isis and Magna Mater

The Sanctuary of Isis and Magna Mater in Roman Mogontiacum was built in the 1st century CE and remained in use until late antiquity. Archaeological remains came to light in 1999 during construction work in downtown Mainz for what is now the "Römerpassage", and were subsequently uncovered in a rescue excavation. Plans to demolish the ancient walls after the excavations were completed were abandoned following public protests; instead, a display room was set up at the site, where the most important architectural remains and selected artifacts are presented in a permanent exhibition. A comprehensive monograph detailing the results of the excavation has not yet been published.
