Rathaus
Passau's looming 14th-century town hall sits like a vast Venetian merchant's house on a small square (called, logically, Rathausplatz) fronting the Danube. The building was once home to a wealthy German merchant, before being declared the seat of city government after a 1298 uprising. Today it holds two council chambers, home to wall paintings depicting scenes from local history and legend, though it's not currently possible to visit these interiors. Even if you don't see the Rathaus, you'll probably hear it, as the tower is home to Bavaria's largest glockenspiel, which plays daily at 11:30 am and 2:30 pm.
