Christiansborg Palace 5.64

Christiansborg Palace is a palace and government building on the islet of Slotsholmen in central Copenhagen, Denmark. It is the seat of the Danish Parliament (Folketinget), the Danish Prime Minister's Office and the Supreme Court of Denmark. Also, several parts of the palace are used by the Danish monarch, including the Royal Reception Rooms, the Palace Chapel and the Royal Stables.The palace is thus home to the three supreme powers: the executive power, the legislative power, and the judicial power. It is the only building in the world that houses all three of a country's branches of government. The name Christiansborg is thus also frequently used as a metonym for the Danish political system, and colloquially it is often referred to as Rigsborgen (castle of the realm) or simply Borgen (the castle).The present building, the third with this name, is the last in a series of successive castles and palaces constructed on the same site since the erection of the first castle in 1167. Since the early fifteenth century, the various buildings have served as the base of the central administration; until 1794 as the principal residence of the Danish kings and after 1849 as the seat of parliament.
