The Bridge Tower Museum is located in the last surviving tower of the historic Stone Bridge. From the top of the fortified tower, visitors have a wonderful view of the bridge, the Danube and of course the roofs of Regensburg's old town.The various aspects of the bridge are shown on the individual floors. For fans of old clocks, there is an old tower clockwork to see. The former tiny tower apartment on the top floor still conveys the cramped conditions in which many families lived in the Middle Ages.
