The Museum of Fine Arts, or Kunsthistorisches Museum, houses the fabulous art collection of the Habsburgs, the royal dynasty of Austria for over 600 years. Emperor Franz Joseph I commissioned the building as part of his expansion of Vienna in 1858, and it took 20 years to build, opening in 1891.
Inside you'll find amazing art treasures including Greek, Roman and Egyptian antiquities, European paintings and sculptures, a coin collection named one of the five best in the world, and a library specializing in Austrian theater history of around 90,000 items. The building itself is also worth seeing with its sweeping staircases and murals.
Take metro line U3 to Volktheater station, or tram D to the Kunsthistorisches stop.
