Rundetaarn

Rundetaarn is a baroque observation tower in Copenhagen's city center standing 34.8 meters tall with a diameter of 16 meters. The interior features a continuous spiral ramp that ascends gently to the viewing platform, circling multiple times around the central axis.

King Christian IV commissioned construction in 1637, and architect Hans van Steenwinckel the Younger completed the structure in 1642 as an astronomical observatory. The innovative spiral ramp was a remarkable solution for accessing the viewing platform during that era.

The library hall inside functions as a gallery space where artists regularly display their work and host cultural events throughout the year. It transforms the tower's interior into an active venue for the local art community.

The tower is easy to reach on foot from the city center and sits in a lively neighborhood with cafes and shops nearby. The spiral ramp is easy to walk, so the climb is manageable for most visitors.

A surprising chapter in the tower's story is Czar Peter the Great's visit in 1716, when he rode his horse up the entire spiral ramp to the top. This feat highlights the remarkable width and stability of the structure that made such an unusual accomplishment possible.
