Lutherkirche, Protestant church in Mainz-Oberstadt, Germany

Lutherkirche is a Protestant church at Zitadellenweg 1 in Mainz-Oberstadt, next to the citadel and above the ancient Roman theatre. Its light brown stone facade has a steep central gable topped by a slender metal cross, a circular window with radiating mullions, and a row of four tall narrow windows, with a metal fence in front.

The Luthergemeinde was founded in November 1930 without its own church, and services were held in halls in the Oberstadt. Construction of the Lutherkirche began only after all three Protestant churches in Mainz had been destroyed. Built in 1949 as the city's first church after the Second World War, it was financed through the Evangelical Church in Germany's emergency church programme and the members' own labour, following a design by Otto Bartning.

The congregation was founded in November 1930 and held services in halls across the Oberstadt until the church was built. The name Lutherkirche ties the community to the Protestant Reformation tradition. Visitors can see the cross rising from the central gable and the round window with radiating mullions below it.

The church stands at Zitadellenweg 1 in the Oberstadt, next to the Zitadelle and directly above the Roman theatre; both structures are protected monuments. Approach on foot from the Zitadellenweg side, where a metal fence runs in front of the gabled facade. The building is a parish church, so visits depend on services and community use rather than fixed opening hours.

The church stands beside the Zitadelle and immediately above the ancient Roman theatre; both structures are listed as monuments. Its address, Zitadellenweg 1, places it on the Oberstadt's edge, where the modern building and the excavated Roman ground lie in direct sequence.
