The town tower or "Stadtturm" stands guard over the north exit of the city. It is the only tower still standing that was used as a stronghold during the mediaeval times. The town tower or "Baderturm" was built in the second half of the 15th century. The steep, tiled hip-roof sports the town's colours of black, red and white in a zig-zag pattern. Today the tower and it's vantage point are used for public events and tours can visited on tours by the town.
