Slotsholmen is an island in the harbor of Copenhagen. One of the most notable and impressive buildings on it is Christiansborg Slot, a Neo-Baroque palace built on the site of the old castle founded by Absalon, a Danish archbishop and statesman, in 1167. Christiansborg is the site of the Danish Parliament today.
Slotsholmen seats many of the central institutions in Denmark. Apart from the Parliament these include Christian IV's Stock Exchange (famous for its dragon spires), the Supreme Court, the Prime Minister's and Minister's Office, the Ministry of Finance, the Royal Reception Rooms, the Chancellery and the Royal Library, and the National Archive. A few museums are also located on the island.
