Entrance to the Upper Belvedere (Oberes) in the Belvedere, Vienna, (Wien), Austria.

"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 3rd district of the city, south-east of its centre. It houses the Belvedere museum. The grounds are set on a gentle gradient and include decorative tiered fountains and cascades, Baroque sculptures, and majestic wrought iron gates. The Baroque palace complex was built as a summer residence for Prince Eugene of Savoy. 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 dynasty. This period of prosperity followed on from the commander-in-chief Prince Eugene of Savoy's successful conclusion of a series of wars against the Ottoman Empire." Wikipedia intro
