Rundetaarn (The Round Tower), Copenhagen, was built on the initiative of King Christian IV (1588-1648). The foundation stone was laid on 7 July 1637 and completed in 1642. The tower was the first stage of the Trinitatis complex, which was to gather three important facilities for the scholars of the seventeenth century: an astronomical observatory, a student church and a university library.

The spiral walk is unique in European architecture. The 209 m long spiral ramp winds itself 7,5 times round the hollow core of the tower, forming the only connection between the individual parts of the building complex.
