Check out the art gallery - and enjoy a coffee in the new cafe.
Europe's oldest functioning observatory, the Rundetårn (or Round Tower) was built under the orders of King Christian IV in 1642, and remains a fascinating piece of architectural engineering. Central to this (and unique in Europe) is the 209 meter-long spiral ramp, which twists around the tower 7.5 times before reaching the top of the 34.8 meter-high tower. With Copenhagen's landscape decidedly lacking in tall buildings, the summit still affords some of the best views over the city. As well as its astronomical purpose, today's Round Tower is home to a modest gallery hosting changing exhibitions as well as concerts.
