Round Tower Copenhagen

Catch a glimpse of history in Copenhagen at the round tower. Part observatory, part church and part library, the round tower - or Rundetaarn - was commissioned in 1637 by King Christian IV to continue the work started by astronomer Tycho Brahe. Today, the Round Tower is one of the most recognisable buildings in Copenhagen, renowned for its distinct architecture and expansive views over the city.

Panoramic views over Copenhagen
Opened in 1642, the Round Tower is the oldest functioning observatory in Europe and still attracts visitors and amateur astronomers from all over the world. Today, the unique building also boasts a gallery space and intimate concert venue in its Library Hall and serves as a hub of culture for both visitors and locals.

Built as part of the Trinitatis Complex, the roof of the tower serves as a panoramic observatory where visitors can see the best of traditional and modern architecture in Copenhagen with a bird's eye view.

Inside the Round Tower also boasts some distinctive features; the impressive 209 metre Spiral Ramp is unique in Europe, winding seven and a half times around the tower's hollow core and forming the only connection between the different parts of the complex.

Visiting Round Tower Copenhagen
The Round Tower is located in central Copenhagen, just a short walk from the Radisson Blu Royal Hotel and other popular local attractions like the Copenhagen Opera House. The tower and observatory is open to visitors daily from 10 am to 5 pm, and is extended to 8 pm during the summer months.
