Rundetårn : info and guided tour

Introduction to Rundetårn

Rundetårn, or the Round Tower, is one of the best-known landmarks in central Copenhagen. Located on Købmagergade, this historic tower is part of the old district’s urban landscape and attracts visitors for both its distinctive architecture and its cultural and scientific function, still perceptible today.

Built in the 17th century, it was designed as an observatory and as part of a complex linked to learning. Its circular plan sets it apart immediately, as does its wide, gradual interior spiral ramp, which replaces the traditional staircase and leads to the upper levels in spectacular fashion.

The site is famous for its views over Copenhagen’s rooftops and for its observatory, one of the oldest in Europe still in use. Inside, the simple, sturdy architecture highlights the continuous ascent to the platform, while the spaces often host exhibitions and cultural activities.

Rundetårn remains appreciated for the clarity of its design and for the contrast between its modest silhouette and its emblematic role in the city. A visit allows you to see the helical ramp, the observation room, and the terrace, which together offer a precise reading of its history and singularity.
