Mainz Cathedral

Mainz Cathedral (Mainzer Dom) is the Roman Catholic cathedral in Mainz, Germany, and an architectural landmark on the banks of the Rhine. The church originated in the late 10th century and is associated historically with the archbishopric of Mainz.

The cathedral exhibits Romanesque architecture with later Gothic and Baroque modifications resulting from successive rebuildings and restorations. Visitors encounter a nave and choir containing episcopal tombs, a Romanesque crypt and an ecclesiastical treasury with medieval liturgical objects.

Originally begun under Archbishop Willigis in the late 10th century, the cathedral has been damaged and rebuilt multiple times across centuries due to fires, wars and renovations, which contributed to its mixed stylistic appearance. It has served continuously as the bishop’s seat for the region.

The cathedral stands in central Mainz beside the Rhine riverfront and is within walking distance of the city’s historic centre and civic landmarks.

• Founding: Construction began in the late 10th century under Archbishop Willigis and the building has been rebuilt and modified several times over the medieval and modern periods.
