Old Town Hall
The first part of this historical landscape was built in 1410 on Schmiedestrasse, the next wing was raised on the foundations of the 13th century trade hall. The other contiguous wing in the Koebelinger Street was rebuilt with an Italian Romanesque style. Inside the building you can see many portraits of princes and the popular game of “Luderziehen”
