Ever since its inception, the Belvedere has been a house of art. At first, it accommodated the collections of Prince Eugene; from 1781, it was home to large parts of the imperial collection and open to the public. The opening of the Modern Gallery in the Lower Belvedere in 1903 paved the way for today's collection. It currently boasts 18,600 works covering 900 years of art history. Highlights of the collection include works from the Middle Ages, the Austrian Baroque and Viennese Biedermeier, and the period in Vienna from around 1900, complemented by works by Claude Monet and Vincent van Gogh with an additional focus on the 20th and 21st century.
