About Rundetaarn

Rundetaarn, the Round Tower, is a seventeenth-century observatory tower on Købmagergade in the medieval core of Copenhagen, and the thing that makes it unusual is that it has no staircase for most of its height. A brick ramp spirals up around a hollow core instead, and that ramp is the only route to the top. The tower measures 34.8 metres from the street to its viewing platform and weighs some 5,914 tonnes. April 1–September 30: daily 10:00–20:00. October 1–March 31: daily 10:00–18:00. December 31: 10:00–15:00. Closed December 24, December 25, and January 1.

What's inside

Four things are worth stopping for on the way up, and the ramp connects all of them. Halfway up, on the floor above Trinity Church, is the Library Hall, 811 square metres under a ceiling 3.85 metres high. It held the University of Copenhagen's book collection from 1657 until 1861, and the Danish three-age system of Stone, Bronze and Iron was worked out in it; the National Museum of Denmark grew out of the collection kept there. The Observatory building reopened for visitor access on August 13, 2026. Staffed telescope-observation nights resume in October 2026.

How long to spend

Allow about an hour. The Round Tower publishes no suggested visit length, so this is a working estimate rather than a figure from the operator, but it holds up against the building's own dimensions. The ramp's outer edge runs 281 metres over 7.3 turns at a gradient of ten per cent, which most people walk in ten to fifteen minutes without hurrying; the two staircases at the top add 28 wooden steps and 31 stone ones. Coming down again is quicker.

Getting there

The address is Købmagergade 52A, 1150 Copenhagen K, and the door opens directly onto the pavement of a pedestrianised shopping street, which is the first thing to understand about arriving. The entrance is at Købmagergade 52 A, 1150 Copenhagen K. Nørreport is the named nearby arrival station, approximately a five-minute walk from Rundetaarn. Nørreport is served by Metro lines M1 and M2, S-trains, regional trains, and buses. The approximately 200-metre Spiral Ramp leads toward the top, but two staircases follow it: a wide wooden staircase and a narrow winding stone staircase.

What to watch out for

The ramp is the whole building and it is also the whole problem. There is no lift, the incline is continuous, and beyond the ramp two flights of stairs, one wide and wooden and one narrow and stone, lead to the platform. A traffic light controls movement on and off the viewing platform and can hold you for a minute or two. There is no lift or elevator. The Library Hall and its exhibitions can be reached without using the upper staircases, although the ramp's incline can be difficult for manual wheelchair users.

Photography

Photography for private use is allowed, with the qualification that it means a phone or a smaller camera in the hand. Setting up equipment, or running anything that amounts to a photo session, needs permission from the Round Tower first, and the tower states that it does not wish to serve as a backdrop for commercial product marketing or for wedding photography. Anyone shooting film or stills beyond a personal record is expected to contact the tower for approval before arriving. The viewing platform cannot be reached by wheelchair or pushchair.
