Marienborg
Marienborg has been the official residence of Denmark's prime minister since 1962. It is frequently used for governmental conferences, summits and other official purposes, including the prime minister's new year speech. Unlike the residences of other heads of government and state (e.g. the White House, 10 Downing Street, La Moncloa and Élysée Palace), Marienborg does not serve as the government headquarters or contain the office of the prime minister, instead Christiansborg Palace is the location of the government departments.
The manor is situated on the shore of Lake Bagsværd in Kongens Lyngby, north of Copenhagen in north Zealand.
