Christiansborg Palace is the seat of the Danish Parliament, the Danish Prime Minister's Office and the Danish Supreme Court. Also, several parts of the palace are used by the monarchy, including the Royal Reception Rooms, the Palace Chapel and the Royal Stables.
The palace is thus the house of Denmark's 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. Christiansborg Palace is owned by the Danish state, and is run by the Palaces and Properties Agency.
The present building, the third to be built on the site, 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. The first castle on the site was Absalon's Castle. According to the Danish chronicler Saxo Grammaticus, Bishop Absalon of Roskilde built a castle in 1167 on a small island outside Copenhagen Harbour. 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.
The palace today bears witness to three eras of Danish architecture, as the result of two serious fires. The first fire occurred in 1794 and the second in 1884. The main part of the current palace, finished in 1928, is in the historicist Neo-baroque style. The chapel dates to 1826 and is in a neoclassical style. The showgrounds were built 1738-46, in a baroque style.
References:Linderhof is the smallest of the three palaces built by King Ludwig II of Bavaria and the only one which he lived to see completed.
Ludwig II, who was crowned king in 1864, began his building activities in 1867-1868 by redesigning his rooms in the Munich Residenz and laying the foundation stone of Neuschwanstein Castle. In 1868 he was already making his first plans for Linderhof. However, neither the palace modelled on Versailles that was to be sited on the floor of the valley nor the large Byzantine palace envisaged by Ludwig II were ever built.
Instead, the new building developed around the forester's house belonging to his father Maximilian II, which was located in the open space in front of the present palace and was used by the king when crown prince on hunting expeditions with his father.
