Round Tower It is one of the most unique and historically significant attractions in Denmark. Located in the heart of the Inner City in Copenhagen, has functioned as both an astronomical observatory, a scientific center, and today as a popular observation tower and cultural attraction since the 1600s.

A visit to the Round Tower is not just a trip to the top – it is a journey through Danish history, architecture, science, and culture, all gathered in one iconic building.

The story behind the Round Tower

The Round Tower was built in 1642 under King Christian IV and was part of the so-called Trinity Complex, which also included Trinity Church and the University Library. The tower was built as an astronomical observatory for the use of the University of Copenhagen and played an important role in the development of Danish and European astronomy.

Christian IV wanted to strengthen science in Denmark, and the Round Tower became a concrete symbol of this ambition. The observatory at the top of the tower was used, among other things, for studying stars, planets, and celestial bodies – long before modern telescopes and space travel.

The unique spiral ramp

One of the most characteristic features of the Round Tower is the winding ramp that leads all the way from the bottom to the top. Instead of stairs, the ramp winds 7.5 times around the tower, making the ascent smooth and accessible.

The ramp was originally designed so that horses and wagons could transport astronomical instruments all the way up to the observatory. Today, visitors can walk all the way up without stairs, making the Round Tower a sight that almost everyone can visit – regardless of age and physical condition.

The view from the top of the Round Tower

At the top of the Round Tower, one of the most beautiful views over Copenhagen awaits. From here, you can look out over the city's rooftops, church towers, and historic buildings, and on clear days, the view extends all the way to the Øresund and Sweden.

The viewpoint is popular all year round, but especially in sunny weather and at sunset, the experience is truly special. Many choose to visit the Round Tower precisely for this view, which provides a unique overview of Copenhagen seen from above.

The Library Hall – Culture and Art in Historical Settings

Inside the Round Tower, you will also find the beautiful Library Hall, which previously housed the University of Copenhagen's library. Today, the hall functions as an exhibition and concert space, hosting art exhibitions, cultural events, and smaller concerts.

The library hall is known for its unique acoustics and atmospheric ambiance, where historic walls meet modern art and culture. That makes the Round Tower much more than just an observation tower – it is also a vibrant cultural center in the heart of the city.

Rundetårn as a cultural and historical icon

The Round Tower has been an important part of Copenhagen's cityscape and Danish cultural history for centuries. The tower is mentioned among other things in H.C. Andersen's fairy tale. The Tinderbox, where the dogs are described with eyes "as big as the Round Tower". This reference has contributed to the tower's status as a popular and cultural icon.

Today, the Round Tower is both a historic building and a modern attraction that draws tourists, school groups, and local Copenhageners. The combination of history, architecture, view, and culture makes the tower one of the most versatile attractions in Copenhagen.
