The Heuscheuer, a medieval communal granary, was built in the 18th century from the ruins of a former corner tower of the city wall.

In 1963, the building was reconstructed and renovated. Today, the Heuscheuer houses modern university lecture halls. During renovation, the staircases leading to former defence towers were rediscovered. One of them is still preserved and open to the public.

Furthermore, visitors should not miss a visit to the halls inside: One of the attractions is a copy of a Roman tomb found in Adamklissi (Romania) dating back to the 3rd century.
