The Round Tower Lookout Tower – Observatory – Exhibitions – Concerts.One of the best-known and most popular structures in Denmark, the Round Tower has been a distinctive feature of the Copenhagen skyline since 1642. The Tower once soared far above the rest of the rooftops in the city, and University astronomers studied the stars and planets from the Observatory at the top. The scholars may have forsaken the building a long time ago, but during the winter visitors are still able to gaze at the cosmos from Europe's oldest functioning observatory. The platform that runs around the outside of the Observatory affords views over the old Latin Quarter – from here, you can spot most of the city's famous buildings. The Round Tower does not have an elevator, so visitors have to climb the winding, white-washed Spiral Walk, where kids often hide in the niches, only to jump out shouting “boo!” as adults approach. Halfway up the tower is the entrance to the large and stunningly beautiful Library Hall, which now serves as a popular gallery and concert venue. It hosts several exhibitions a year, and stages concerts almost every week. Above the Library is the Bell Loft, notable for its enormous wooden beams, which were used in the reconstruction of the Tower following the great fire of Copenhagen in 1728. The Loft is also home to a small exhibition of fascinating artefacts from the Tower's history, including Christian IV's wax seal, a tin of medicine produced by Tycho Brahe, and a piece of the bomb that exploded in the Library Hall during the bombardment of Copenhagen in 1807.The Round Tower was built by Christian IV between 1637 and 1642. It was the first part of the Trinitatis Complex, which combined church, library and observatory in a single building.

One of the few tall buildings you can go up and get a half decent view of this low rise city. Very good value and a nice gentle climb up the slope to the top. Avoid if it's raining.

A lot of stairs, but the view of the city is amazing from the top! Try to go when it's a sunny clear day (or as close as you can get).

Another one of King Christian the 4th's projects around the city. Great history and an even greater view on a clear day. An easy to walk to from Norreport St.

For a bargain price you can see Copenhagen from a different angle. A gentle stroll up the inside of the tower takes you past the library where Hans Christian Andersen studied, past the planetarium, and allows you to stand at the centre of Denmark, and see across to Sweden.

Very nice view of Copenhagen and very interesting surprise in the form of a spiral ramp instead of stairs. I've never seen spiral ramp like this. Nikol Hasova

A little bit of a hike up to the top, but well worth it! There is a glass in the middle of the stairs which you can stand on and look down and see all the way down to the bottom. It is hidden but it's very cool!

Reasonable entrance price. Interesting and unique building and experience. Good exhibition in one of the rooms as you walk up. Secure and safe viewing platform and good roundabout view of the city.

In the city centre, shops around and the tower just there. It's lovely to go up and see from the top. A café is someway in the middle of the stairway.

The tower is almost entirely climbable by the spiral ramp and so is quite interesting to climb. The climb includes an art gallery half way up and the views from the summit span much of central Copenhagen, with many iconic buildings visible in the skyline. The top of the tower is surrounded by two lines of railings which makes it... More

Really enjoyed visiting this - good for all ages as our boys could run up a little ahead of us and we knew they couldn't go anywhere! Lovely views at the top and managed to burn a few calories in the process!
