Vienna has the remarkable MuseumsQuartier to thank for its existence - a museum made possible by the efforts of ophthalmologist Rudolf Leopold. As a young student in 1950, Leopold bought his first Egon Schiele for a low price, and his collection grew to include an impressive 5,266 paintings, primarily 19th-century and modernist Austrian artworks. In 1994, he sold his entire collection to the Austrian government for a sum of €160 million - a price that was around one-fifth of the collection's actual value. On the top floor of MuseumsQuartier, visitors can also enjoy Cafe Leopold, a hip bar.
