Christiansborg Palace is a building in the Danish capital, Copenhagen. It is the seat of the Danish Parliament, the Office of the Prime Minister, and the Supreme Court. The first castle on the site was Absalon's Castle, built in 1167 by the bishop Absalon and demolished in 1370, after King Valdemar was defeated by the Hanseatic League. By the end of the 14th century Copenhagen Castle was built on the site but that too was demolished in 1731. The first Christiansborg was then built, on the orders of King Christian VI, becoming the largest palace in northern Europe on its completion in 1745. It was destroyed in 1794 by fire, and replaced by the second Christiansborg. That too burned down in 1884, eventually being replaced by the current building, which was built between 1907 and 1928. The modern building is neo-Baroque in style, although the 19th-century neoclassical chapel and the original Baroque riding grounds remain, having survived the fires.Photograph: Julian Herzog
