Round Tower

Visit one of Europe’s oldest functioning astronomy observatory towers, which is now also a cultural center and a good vantage point to see Copenhagen from above.

Looming above Copenhagen’s central pedestrian mall is an iconic 17th-century observatory named Rundetaarn (Round Tower). Climb to the top to enjoy the 360-degree views of the city or join aspiring astronomers for stargazing. The Round Tower complex also houses a gallery, concert hall and even a picturesque church.

Built under the guidance of Christian IV in the early 1600s, the Round Tower is still one of the most notable works of architecture in the city. This was once an astronomical research facility for the University of Copenhagen, but it is now a cultural center for all to enjoy.

A steep ramp wraps around the central interior column, a stunning example of the advanced architecture for the time. Hike to the top and catch your breath while viewing exhibits at several rest areas along the way.

Halfway up is the Library Hall, a cultural center. Browse exhibits of contemporary art, scientific wonders and works of local students. This is also a concert venue. Take advantage of the weekly opportunity to listen to local jazz, classical or folk music in this special setting.

Continue up the ramp to the observation deck, situated at 111 feet (34 meters) above the street. Order refreshments from the kiosk, take a seat on a bench and observe the activity in the idyllic harbor in the distance. 

A narrow, steep staircase leads to the observatory. On a Sunday afternoon in summer you can usually come here to stare at the sun through a solar telescope. Aspiring astronomers can also visit the observatory during selected evenings to gaze at the stars and learn about faraway constellations. Check the tower’s website for details.

The Round Tower is located in central Copenhagen and is best reached by bike or on foot. The Nørreport metro station is nearby and there is limited street parking for a fee surrounding the station. The Round Tower is open daily from March through October, with additional evening hours during summer. There is a small fee for admission. Note that there is no elevator.
