Owner description: 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.

“A great way to discover Copenhagen”
Reviewed 4 September 2010

I have to admit - Any cities that I go to - I have to go to a tower or high point to get a feel for the architecture / scenery that a city has to offer: rooftops, bridges, main attractions,... I was not disappointed with my visit at the Rundetaarn.

Covered by the Copenhagen Card, this round tower is different than many of the other "high" places that I have visited throughout Europe. To get to the top, most venues will either have elevators or stairs - this place is different as you just walk in circles to the top (no stairs), with a few opportunities for stopovers (mini-museum, gift shop, "original" toilet,...)

The views from the top have to be amongst the best in Copenhagen. On a relatively clear day (and at times with a good zoom) you have great views and can catch great pictures of the Malmo Bridge, Tivoli Gardens, some of the castles / churches and just Copenhagen in general.

We went late in the day and the views were magnificient.

Information about the tower is available in many languages, including English.

“Unique architecture!”
Reviewed 29 July 2010

The Rundetaarn, or Round Tower, was built during the reign of King Christian IV - the same guy who commissioned and lived in Rosenborg Castle. It's approximately 11 stories tall, and a circular platform on top of the tower offers sweeping, unobstructed views across all of Copenhagen. It was the Space Needle of the 17th century.

The unique feature of the Rundetaarn is the wide, spiral ramp that corkscrews continuously from the street level to the top. Apparently, King Christian IV did not want to climb up an extremely long series of stairs, so the ramp was designed to be large enough to accommodate a horse and carriage. During the time, an astronomical observatory and a library were also located at the top. A large clockwork planetarium is still up there, showing the position of the planets relative to the zodiac. A church was also added to the side of the Rundetaarn soon after its completion.

Walking up the ramp was fun. It completes seven and a half revolutions over 685 feet. The view from the top allowed me to see the row of large windmills in the sea and the Oresund Bridge to Sweden, which is nearly five miles long! The bird's eye view also helped me to appreciate the organic layout of the city's streets. Despite the seemingly haphazard arrangement of the buildings, there's a certain neatness and cohesiveness to it all that doesn't exist in most American cities. The one thing I didn't like is the featureless horizon. Copenhagen is absolutely flat as far as the eye can see - which is great for bikes - but I'd miss the scenic hills and mountains of the Pacific Northwest.

“Unique building from 1642, magnificent view of CPH for only 25 Krone.”
Reviewed 12 June 2010

It's every Krone worth climbing up the slope. Especially recommended when the weather is good. I wouldn't go up there when it's raining. Wonderful overview of the city. There is an exhibition hall in the middle. The visit to the exhibition is also included in the fee. It is a little difficult to find the entrance when you are deep into the window shopping, it's just about 200m off the sloget (the longest shopping street), look upwards to find the round brick tower.

“Its Round”
Reviewed 28 May 2010

The Round Tower is a quick, easy and cheap thing to do when you are walking around the Stroget. It is an easy climb up a ramp to the top with a only few stairs at the top. The view is great.

“Good to get your bearings”
Reviewed 28 May 2010

This beautiful building is enjoyable for all ages and set right in the centre of Copenhagen. The view at the top is spectacular and gives you a great sense of where you are. Make sure you go into the rooms on the way up as there are numerous exhibitions which give a sense of both modern and old Copenhagen.
