Old town

The historic centre of Copenhagen encompasses several buildings, most built in the Renessaince, baroque and neoclassical period. Some of these buildings look older than they are. For instance the town hall and the Palace hotel were built at the beginning of the 20th century. The Christiansborg Palace/Castle on the islet of Slotsholmen seats the Danish parliament and was built in 1928 on the site of a previous structure which has been destroyed by a fire (first structures built in 1167). The 17th century Amalienborg palace is the winter home of the Danish royal family. The Børsen (first built in 1640) housed the Danish stock-market until 1974. The Rundetårn is a 17th-century tower which was built as an astronomical observatory. It contains a 7.5-turn helical corridor which leads to the top. The Ny Carlsberg Glyptotek is a 19th century art museum which contains sculptures from ancient Egypt, Greece and Rome as well as more modern art (French impressionism and Post-impressionism, Danish Golden Age).
