The Round Tower Lookout Tower – Observatory – Exhibitions – Concerts.One of...

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.

Centrally located, this tower provides stunning views of Copenhagen and is fun to walk up (and a great opportunity for getting some cool pictures!) I'd highly recommend it and it's worth the 25 Danish Krone to go to the top. I do wish they had pieces of information about the building's purpose and history!

We went on a foggy January day, so we knew the view wasn't going to be the best, but as we were using our Copenhagen Cards to get in we didn't mind. Climbing the tower was different to the many church towers we have done because the majority of the tower is made up of one long winding slope -... More

We really enjoyed climbing up this tower as the reward was the fantastic views from the top. I'm not very fit and I found it ok as it is a gentle slope (with a few steep steps at the top) there are also toilets and a kind of gallery /library so far up if you want a drink or a... More

I had a 2-3 hours walk in the downtown and the nearby districts. On the way back to Nørreport I stopped to have a look on the tower. It was a bit chilly day, so I decided to get in. There is an awesome souvenir shop with coffee house, plus a great exhibition. On the top, the view is wonderful,... More

A good piece of history to visit off Stroeget, I have visited most historical places in Copenhagen due to going school in Copenhagen, this is one of the Locals favourites definitely. It is also been used in many Danish films and Series! Even the infamous Olsen Banden featured den runde taarn. Maybe I am biased but if you love Copenhagen... More

We all enjoyed our visit to the "round tower". Conveniently located on one of the many walking streets, (with a selection of Polse vendors close by) we all enjoyed the easy walk to the top of the tower, stopping along the way to check out an architecture exhibit, and to take photos out of the many windows. The view at... More
