About
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.

The area
Address
Neighborhood: Indre By (Inner City)
This is the heart of old town Copenhagen, with its blend of charming old buildings and bold new architecture, broad avenues and tiny streets as well as picturesque canals and a modern harbor. The inner city is home to the Royal Danish Theatre, which consists of three buildings, two of which are new and situated on the harbor front. The streets, squares and venues of the inner city and its surrounding neighborhoods, are alive all year round with everything from jazz festivals to outdoor ice skating rinks and parachuting at the lakes right in the center of the city. This compact area boasts beautiful old castles, tranquil parks, and bustling squares where you can always find a bench to stretch out your legs whenever you need a break.

    Round Tower
    Located off a side street from Stroget, the Round Tower, a 17th century astronomy tower has interesting interior architecture. The tower is attached to the beautiful Trinitatis Church, however ticketing is only valid for visiting the tower. We visited ticket-free as part of our Copenhagen Card. In addition to the viewing platform at the top, entry ticket to the round tower includes a visit to an exhibition hall (space exploration theme was on during our visit), another hall showcasing the brief history and architecture of the building and a look at an old toilet for the round tower. There were some stairs towards the top but otherwise the whole tower is "sloped". Free toilets and small souvenir shop inside the tower.

    Visit the observatory!
    We went up in the evening on a night when the observatory at the top was open. The tower itself is interesting having a ramp instead of lots of steps. There is a small display room off to one side that shows the construction, the enormous beams. Copenhagen is not the prettiest city to view from up high and it is not a great place for night views either, but when open, you can visit the observatory. It was a nasty night and so cloudy that the volunteers did not even open the dome, but it was still great to get in there and see such a tiny observatory and how it all works. The volunteers were enthusiastic about answering questions. There is no extra cost for the observatory, so it is well worth timing your visit for when it is open.

    Very Interesting and Enjoyable
    Cheap entry to the tower, very informative exhibits about the tower off in the side rooms as you go up and there was a free art exhibition in a room part way up when we visited. The view at the top is lovely and I had just been expecting a nice view to be honest, so to come away having learned a lot about the tower and its place in Denmarks history made it a very worthwhile visit. Very much worth the 25kr entry fee.

We visited Rundetarn in the evening as the sun was starting to set it was a lovely view over the city of Copenhagen. The walk up was fun and was nothing like any other tower we have visited. It was nice to stop along the way and look out the windows and they had a cafe and small bell room to view along the way. The story behind the tower is fun and they also have an observatory at the top which you can view. Well worth a visit if you are in the city and ot is a reasonably priced activity.

Nice to experience to see inside the tower. It's 17th century tower located in the city center in Copenhagen and its iconic building which houses exhibition experience and the tower attached to a nice church. It takes a 3 minute walk to the top. There is nothing much fancy to see around and if you want to see the nice view of Copenhagen from above coupled with the nice sunset, this place a must to see. The entrance cost 40kr per adult. The place open at 10:00 and closes 20:00 pm during summer. From October to March open at 10:00 and closes at 18:00 and its open everyday except Christmas holidays.

So often, (perhaps in an effort to NOT look like a tourist), we don't take the time to look up when visiting a new city (although in this case it could also have been the rain). Because of that, I actually went past this tower twice before noticing it was there!! When I included it on a day's ramblings I was surprised it was hiding in plain site and that it is much more than it appears from the outside. For a small a fee, (25kr...I think?) you can walk up the ramp inside, (not stairs), to the top and the view is beautiful. There is also access from the tower to the church "attic" with a wonderful, small but informative exhibit of the tower's history & construction. I'm very glad I made a point to seek this out and spend some time (roughly an hour) here. There was also a fun activity for kids while I was here, that required them to find and learn about real and & literary animals! Very cute!

Although not recognised as a "must do" when you think about visiting Copenhagen i would highly recommend that you do!!

Set on the pedestrianised shopping street in the city centre you can climb the wide, cobbled spiral to the very top (around 35 metres from ground level). On the way up there are some really interesting things to see including the bell tower an old 'privy' and a glass floor to stand on and show how far you have climbed.... Upon reaching the top you are treated to a fantastic view above the rooftops of the city. There are really handy plaques pointing out what you can see from each angle. You really can see for miles and it is very cheap.... Highly recommended!!

Not expensive, part of the city’s cultural identity . Built so the king could take his horse to the top makes this spot worth the effort.
It is a struggle if you’re not fit but you can take your time. Don’t forget to look down the well on the way up. With its glass floor situated near the top in the centre column.
The views from the top are superb. Short half hour visit at a low cost will tick another attraction off you list.

This tower is something to visit in Copenhagen.
It’s a round tower with no stairs, so it’s very easy to go up. The tower is a XVIII century building, divided in three parts: the first stop is a museum/library/gift shop with different installations from contemporary artists. The second stop is the bells room, and last but not least there’s the third stop with the astronomical observatory and a 360 degrees overview outside the tower.
I really recommend this place, because it’s fast, cheap (3€more or less) and easy also for families with children.

360-degree view of Copenhagen from the top observation deck. Family-friendly venue. If required, you can sit on any of the window ledges winding around the tower. The is also a large hall with a gift shop, a few exhibits, and tables and chairs half way up.

This is certainly a unique Tower, unlike anything I’ve experienced before.
There’s a small entrance fee of £4.50 to enter the tower, you’re unable to purchase tickets online but we were able to buy them at the entrance by a hospitable young woman.
As it’s an equestrian staircase going up Rundetårn there’s no steps until you reach the top of the tower where you have to take a narrow staircase to reach the viewing platform which works on a traffic light system, so it avoids any pedestrian mishaps. There’s also a telescope in an observatory at the very top which you can view and take pictures of but you can’t enter it unfortunately. The 360 views at the top were lovely but nothing groundbreaking. Just before you reach the top, there’s a small, hidden entrance to the centre of the tower with a glass bottom so you can appreciate the height you’ve ascended but it’s very easy to miss- so keep an eye out!
There’s a quaint cafe/gift shop on the same level as the museum, which is located about halfway up the tower.
Overall, I would recommend visiting the tower as it’s different and not far from the main shopping street but I wouldn’t class it as a must see.

After a 6 day whirlwind tour through Copenhagen, I can say that Round Tower had, by far, the best views experienced. Worth 2x the price of admission (probably one of the few in Copenhagen that charges less than I'd be willing to pay!)

Go in the afternoon on a sunny day for the nice shots of Marble Church and Rosenborg and Nikolas Church. Go in the mornings for the best views of City Hall and south City Center. We went in the late afternoon and only the first half mentioned had good lighting.

We walked back to the square with the city hall in and did some photos then took a very meandering route to the Round Tower. Sofia still wasn't sure about going in but I dragged her and we slowly spiralled our way to the top. There were lovely views from the top to the Oresund Bridge and the art gallery downstairs was great too. Very relaxing and accessible modern art. The actual building itself is fascinating too with lovely old windows and a brick tiled floor that makes for an interesting texture. The bell tower exhibit was interesting too and everything was also in English. Certainly well worth the £2.50 fee.
