The two Belvedere palaces were built in the early eighteenth century by the famous Baroquearchitect Johann Lucas von Hildebrandt to be used as the summer residence of Prince Eugene of Savoy (1663–1736). One of Europe's most stunning Baroque landmarks, this ensemble – comprising the Upper and Lower Belvedere and an extensive garden – is listed as a UNESCO World Heritage Site. Today the Belvedere houses the greatest collection of Austrian art dating from the Middle Ages to the present day, complemented by the work of international artists such as Claude Monet, Vincent van Gogh, and Max Beckmann. Highlights from the holdings Vienna 1880–1914 are the world's largest collection of Gustav Klimt's paintings (including the famous golden Art Nouveau icons the Kiss (Lovers) and Judith) and works by Egon Schiele and Oskar Kokoschka. Key works of French Impressionism and the greatest collection of Viennese Biedermeier art are further attractions on display at the Upper Belvedere.The Lower Belvedere and the former Orangery are venues for top temporary exhibitions. These shows focus on presenting Austrian art in an international context, as defined in the Belvedere's original mission back in 1903 (when it was founded as the Moderne Galerie). They comprise retrospective shows of Austrian artists, based on research into their work and significance, and major thematic exhibitions exploring key movements and epochs in art.
