Fodor's Expert Review Veste Oberhaus

The powerful fortress and summer castle commissioned by Bishop Ulrich II in 1219 protects Passau from an impregnable site across the river from the Rathaus. Today the Veste Oberhaus is Passau's most important museum, containing exhibits that illustrate the city's 2,000-year history. From the terrace of its café-restaurant (open Easter–October), there's a magnificent view of Passau and the convergence of the three rivers.
