Rundetarrn means Round Tower in English and that’s literally what you’ll do here, go round and round and round and round! The spiral walk in the Rundetaarn is totally unique in European architecture. The 209 meter long spiral ramp winds itself 7.5 times round the hollow core of the tower. In 1726, Russia’s Czar Peter the Great climbed the circular path on horseback while visiting Copenhagen and his wife rode behind him in a two-wheeled carriage.

Located halfway up the tower is the entrance to the stunningly beautiful Library Hall, which now serves as an exhibit gallery and concert hall. Hosting several exhibitions a year and weekly concerts, this is a perfect place to warm your bones on a winter day.
