St. Martin’s, now a Catholic parish church, is considered a vivid example of a medieval church of a mendicant order. Built at the beginning of the 14th century as a Franciscan monastery church, it was expanded as early as the 15th century and finally dissolved by the French at the end of the 18th century. Today St. Martin's Church is a Catholic parish church. An architectural emphasis is the choir with its ribbed vaulting makes and a length of 21 meters. The baroque ceiling is from the 18th century. The statue outside the west door represents St. Nepomuk - the bridge saint. It was made at the beginning of the 18th century and previously stood on the so-called "Scherbrücke", a nearby bridge over the Lauter, which today flows underground. Behind, in the rectory garden, gravestones preserved from former cemeteries can be seen. The area is still bounded by remains of the medieval city walls.
