The Rundetårn (or 'Round Tower' in English) is perhaps the best place in Copenhagen to enjoy panoramic views of the city’s skyline with its fairytale old town and many spires. The observation deck is located 35 meters (115 feet) above street level, offering an expansive view of inner Copenhagen
The tower was built by King Christian IV, the famous architectural innovator of Denmark, to be an astronomical observatory. A wrought iron lattice runs along the edge of the platform, featuring Christian IV’s monogram. The Rundetårn was mentioned in two Hans Christian Andersen fairytales and is commonly used as a metric to compare heights of buildings in Denmark.
