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 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.
