round Tower
Rundetårn is one of Copenhagen's most famous and iconic sights. It was built in 1642 by Christian IV as an astronomical observatory and is today one of the most visited attractions in the capital.

Rundetårn is a 35 meter high round building that has a unique architecture. The building has a wide spiral ramp, called Sneglegangen, which runs from it the entrance on Købmagergade and up to the stairs that lead to the top of the tower. The corridor winds 7½ times around the tower's hollow core, and is the only way to the top of Rundetårn. The snail passage gives access to the Library Hall, Ringerloftet and the hollow core. It is partly because of this time that Rundetårn is perhaps the most iconic building in the whole country, as it is the only one of its kind here at home.

The tower was originally built to help astronomers observe the movements of the stars and planets. The tower also had an important role in connection with the University of Copenhagen, as it was used as a book store where the students could access books and manuscripts.
Today, Rundetårn is a popular tourist destination and a place where visitors can experience some of the most amazing views of Copenhagen. From the top of the tower you have a fantastic panoramic view of the city, and it is one of the best places to take photos of Copenhagen's skyline.
