Since opening in 2001, Vienna's Museum Quartier (Museumsquartier, or "MQ") has been home to a variety of first-rate museums that are well worth exploring. 

A mix of old and new architecture centered around an area that once served as the former royal stables, it's easy to spend the best part of a day (or two) here.

Must-visits include the famous Leopold Museum, noted for its large collection of works by Austria's leading modern artists, such as Gustav Klimt and Egon Schiele, and MUMOK, the Museum of Modern Art Ludwig Foundation Vienna, featuring more than 10,000 contemporary and modern pieces by renowned artists including Picasso and Warhol.
