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.

On the way up to the top from where you can view the city from above, there are little bits of info about the tower and observatory. On certain days it is possible to get to the top to the observatory and look to the sky.

We loved rundetaarn, the climb was unique and easy, the price was cheap and the view at the top lovely. The exhibition of broken relationships that was on whilst we visited was an added bonus.

The climb to the top is via an unusual circular cobbled slope within the tower which makes climbing to such a great height a really easy feat. Only the last section is via steps which become narrow at the top requiring caution when passing people en route back down! The current exhibition part way up is "Of Broken Relationships'!!! Most...

So this is a fairly easily accessible site and has a very good view for photographs. It does have some historic charm and don't just run in and out but make sure you stop by each of the rooms on the way back out of the building.

The Danish king is said to have ridden his horse up this tower! I will always appreciate my trip inside to experience the views over central Copenhagen!

You get a nice little workout hiking up the spiral road. Along the way you can see the changing views. There's an interesting history to the tower. There's also a chapel in it. From the top, you have some wonderful city views. It was around the corner from where we stayed and we enjoyed walking by it every day.

We always look for somewhere to get a view over a city when visiting & this is the place for Copenhagen. Unusual helter skelter style spiral walkway up to the top. I'm not great with heights, but felt comfortable up there. Also loved the exhibition of broken relationships. Some sad, some funny, some need to get a life!

The tower's unique ramp, designed to be used by horse and cart through the interior of the tower, hides an interesting feature. Through one of the doors in the centre of the tower, one can access a room with a transparent floor. This floor (not for those with fear of heights) allows one to see the inner construction of the...
