Vienna's Kunsthistorisches Museum is housed in a magnificent building created expressly to show off the tremendous art collections of the Hapsburg royal family. 

The superb collection of Dutch art features the world's largest collection of works by Pieter Bruegel the Elder, including his masterpiece Tower of Babel. There are also paintings by Raphael, Titian, Bellini, Caravaggio, and Vermeer, plus portraits by Velazquez.

The museum's specialties are late Italian Renaissance, Baroque, and Flemish painting, but the collections go far beyond those with classical Greek and Roman art and Egyptian collections. Guided tours are available. Worth a visit is the museum café, especially for its atrium setting and tall, elegantly decorated walls and ceiling.
