The oldest church in the city. The church probably stands on the site of a former Carolingian royal court and parts of it date back to 1247. Originally late Romanesque, it was later expanded in the Gothic style and houses several sights, including the late Gothic tabernacle, the war-damaged corpus of Christ and the baroque high altar. This is one of the reasons why the church, which has a two-bay, three-aisled late Romanesque hall with a transept that is only wider than the nave by the thickness of the wall and a 75-meter-high tower, is considered one of the most beautiful in the region. The attentive observer may notice when looking at the west side of the tower that an old cannonball from the First World War is still stuck in the walls.
