The castle of Reisensburg hovers over Danube on the Reisen hill. Already during the Roman times there was a watch tower standing here. In the 10th century the hill and the fortress on it became a part of Bavaria. After that this castle has often changed owners. The powerful Austrian rulers of Habsburg were one of them.
The last private owner of Reisensburg was a local lawyer named Vogel, whose widow devised the castle to the state. In 1966, after her death, an international institute of the scientific cooperation of Ulm University was placed in the castle. The present image of the Reisensburg castle reminds of the 17th century. It was then that the majority of its facilities were built, including the main building and auxiliary facilities. Preserved until our days is the Roman tower into which the castle is literally built in. A wonderful view opens on the vicinity from the tower: Jura hills, Swabia-Bavarian plateau, the town of Günzburg, rivers Günz and Danube.
