Glasmuseum Passau
The world's most comprehensive collection of European glass is housed in the historic Wilder Mann complex. The proud history of glassmaking in Central Europe—centered on Germany, Austria, and the Czech Republic—is captured in more than 30,000 items, half of which are on display at any one time across the 35 rooms. Opened in 1985 by (rather randomly) Neil Armstrong, the museum is home to everything from beautiful baroque creations to eye-catching art deco pieces.
