Passauer Glasmuseum

Opened by Neil Armstrong, of all people, Passau's warren-like glass museum is filled with some 30,000 priceless pieces of glass and crystal from the baroque, classical, art nouveau and art deco periods. Much of what you see hails from the illustrious glassworks of Bohemia, but there are also works by Tiffany and famous Viennese producers. Be sure to pick up a floor plan as it's easy to get lost.
