The Belvedere Castle is one of the masterpieces of Austrian Baroque architecture and one of the most beautiful princely residences in Europe. It was built by Johann Lucas von Hildebrandt for Prince Eugene of Savoy and consists of two opposing palaces, the Upper Belvedere (Oberes Belvedere) and the Lower Belvedere (Unteres Belvedere), separated by a great perspective of French gardens sloping down the hill and overlooking the city. Famous are the views of Canaletto, which depict the place. In the interiors of both buildings is the Österreichische Galerie Belvedere, one of Vienna's leading art museums.
