Passau
On the left bank of the Danube rises the Veste Oberhaus. The castle, perched on the Georgsberg from the 13th century, now houses a museum that deals with the city's history. The permanent exhibitions include collections of Passau porcelain and exhibits from the Middle Ages. In St. Stephen's Cathedral in Passau's old town, you can admire the world's largest cathedral organ with 229 registers and almost 18,000 pipes. It is more sophisticated on the Inn promenade, where numerous cafés entice. Ludwigsstraße, together with its side streets, forms the pedestrian zone where most of Passau's shops are located.
