The Belvedere is a historic building complex in Vienna, Austria, consisting of two Baroque palaces (the Upper and Lower Belvedere), the Orangery, and the Palace Stables. The buildings are set in a Baroque park landscape in the third district of the city, on the south-eastern edge of its centre. The Belvedere was built during a period of extensive construction in Vienna, which at the time was both the imperial capital and home to the ruling Habsburg dynasty.
