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.

25 DKK and you're in, cheap I would say On the top you get to have a "360 degrees" view of the city with its roofs, parks and sea It is windy up there, be prepared You can reach the "astronomy room" where in the past they used to observe the sky with its stars and planets

Entry fee was basically £2.50 each for me and my wife which turned out to be excellent value for money. The climb to the top wasn't too taxing and was broken by a couple of displays. Great views from the top. Worth a visit.

Because the King who commissioned this also didn't fancy the climb, rather than the usual steps, the Rundetaarn was designed for a horse and carriage to ascend so it's a gentle up high climb to the top. As well as the lack of steps, The tower is light with windows peppering the way and acting as little rest points (the... More

The Round Tower is a belltower which was built as a royal observatory. You walk up to the top on a spiral ramp from which you can see views of the city. There is an exhibition about the tower and a perspex platform you can stand on and look down several metres (scary). We were lucky to arrive in time... More

We didn't know much about Copenhagen before we set off into the city so we just bumped into the round tower. It has a cheap entrance fee of 2.5 krona for an adult, and it was well worth it. Great view, good little snippets of information. Most importantly, they had good clean, and at the time, queue free toilets.

The tower is in the middle of the city center right in the shopping streets. You can walk in, pay 25DKK (first rather cheap attraction that I found) and you walk up, any time of day and also in the evening. Very nice! If I'm being honest I don't think there are a huge amount of the normal standout tourist... More

The Rundetaarn or Round Tower is right in the middle of the Old City and has an observatory at the top. The reason it is accessible for the entire family is because the tower has a spiral ramp, so even if you have a baby in a pram, you just push the pram up the ramp! It costs just under... More

I love a good tower, and this was pretty good. Only stairs right at the top, otherwise a ramp. Quite busy but coped well with the demand. Worth a look!

You get almost all the way to the top via a spiral incline which is almost wide enough to drive a car to the top. Great view of the city from the top. Included in the Copenhagen card if you have one.

A bit of a climb, but well worth it for the 360 degree view of Copenhagen. Interesting artefacts and you can get a cold drink if you reach the top
