St. Johannis

St. Johannis is an early medieval church in the old town of Mainz with its original interior spaces still preserved. The building displays typical Carolingian features with straightforward, solid structures that remain in good condition.

The church was built in the early Carolingian period and first served as a residence for the archbishops of Mainz. When the bishops later constructed Mainz Cathedral, this building lost its residential function but remained important as a religious center.

The building shows how Mainz once served as a center of religious authority, with its structure reflecting the importance of the archbishops who worked here. Walking through the rooms, visitors can sense the connection between this place and the power that shaped medieval German history.

The church is located very close to Mainz Cathedral, making it easy to explore both buildings during one visit. Walking through the area helps you understand the medieval layout of the old town.

This building is one of the few surviving structures from the Carolingian period in the region, offering rare insights into early medieval architecture. Its chamber layout shows how living and prayer spaces were once connected.
