This Gothic town hall tower stands where three rivers meet in a Bavarian city — the Danube, Inn, and Ilz. Flood marks on its walls tell stories of centuries of high water.

The Altes Rathaus in Passau dates to the 14th century and features a distinctive painted facade and a tower with a large red clock face. The city of three rivers has been a major trade crossroads since Roman times. Flood markings on the tower walls record some of the most devastating floods in European history.
