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.

Worth the vlimb

The view were pretty good, and the walk up the gentle sloping walkway was OK, so it was worth visiting. The climb was much easier than expected.

The walk up through the Rudentaarn is a bit tough (it's a long, spiraling ramp), but it is absolutely worth it! There are little museums along the way to stop in on your way up, and the view at the top is amazing! Everyone will enjoy this place, highly recommend!

make sure you have comfy shoes on as very small cobbles up the slope, though the top part is VERY steep steps, then a narrow curve staircase that gets very cramped with impatiant people, view from the top is ok but is mainly just the roofs, I was there dusk and the view wasn't that good so go in the...

It only costs 25DK each to experience the tower. It has a brick slope for the most part which made climbing up and down very easy until you got to the last few flights of stairs. Along the way you can visit the church as well as collections as you go up. The view of Copenhagen at the top was... More

The easy slope makes getting up the tower relatively easy. It takes you about 90% of the way up. Once near the top you can see into the loft of the church or one floor down an art gallery. At the very top you can get out on to a large balcony to see 360 views of cooenhagen.

Nice way to spend an hour and good views of the city from the top although on a cloudy day there is not a great deal too see. Would recommend to those wanting to do something a different

Never seen anything like it. An interesting way to climb a tower - a path all the way up! Steps at the very top are narrow and get tight at busy times (no one seems to like to wait either to all you to descend or ascend)! View well worth it though

Very interesting building. I have never seen a tower that had a slope instead of steps before. There are a couple of exhibitions in there too. When we visited there was a large display of items donated by people from their failed romances!

Its a most unusual tower to ascend as all except the last couple of revolutions are almost street width and a paved slope rather than steps. It makes it a very easy ascent. It is very well kept and has good clean toilets and a café. It would get 5 stars if the view was like from the top of,... More
