This wonderful building that has been turned into a restaurant includes the remains of the historic city wall that has protected the city through the centuries. The wall was built in the year 1392, and unfortunately has not been preserved, so what remains of it is a small part that testifies to the greatness of what was. Visitors come to this building from all sides to see it and learn about its history, then they go to eat a traditional German meal in the luxurious restaurant that made the wall one of its facades.
