Stiftskirche St Servatius

This 12th-century church is one of Germany’s most significant from the Romanesque period. Its treasury contains valuable reliquaries and early Bibles. The crypt has some early religious frescos and contains the graves of King Heinrich I and his widow, Mathilde, along with those of the abbesses. From 1938, the church was occupied by the SS, under Heinrich Himmler, Hitler's right-hand man.
