Kunst­historisches Museum

Probably the best museum I've ever been to. Absolutly humongous. A beautiful building in a beautiful city. Don't miss the Kunstkammer on the first floor -- one of the most unique collections I've seen. The Egyptian, Greek, and Roman collections are also amazing. They have a large collection of works by Peter Bruegel the Elder, along with lots of Reubens other Flemish, Dutch, and Italian Baroque and Renaissance paintings. All well worth seeing.
