The sanctuary of Isis and Mater Magna is one of the main attractions of Roman Mainz and a landmark of the city and the surrounding area. The temple in Mainz is the only excavated building of this kind dedicated to Isis in Germany. From the Taberna archaeologica on the ground floor of the passage, descend the steps to the archaeological site. In the multimedia room, visitors can expect to see the foundation of the sanctuary, consecration and sacrificial offerings, escape tablets and many other preserved remains. The operation of the presentation is financed by the Initiative Römisches Mainz as a non-profit association from membership fees and donations.
