The Round Tower (Danish: Rundetårn) is a 17th-century tower in Copenhagen, Denmark, one of the many architectural projects of Christian IV. Built as an astronomical observatory, it is noted for its equestrian staircase, a 7.5-turn helical corridor leading to the platform at the top (34.8 meters above ground), and its views over Copenhagen.
