The Round Tower (Rundetaarn), Copenhagen
A 17th‑century spiral observatory where royal science, city views and contemporary culture coil together above Copenhagen’s old Latin Quarter.
Rising above Copenhagen’s old Latin Quarter, the Round Tower is a 17th‑century astronomical observatory turned cultural landmark. Built in 1642 by King Christian IV, it is famed for its wide spiral ramp that coils gently to a rooftop viewing platform with sweeping city panoramas. Along the way, the former university Library Hall hosts changing art, culture and science exhibitions, concerts and events, making this brick tower a rare blend of history, architecture and contemporary creativity in the very heart of the city.

Local tips
- Arrive close to opening time or later in the evening to enjoy the spiral ramp and viewing platform with fewer people, especially in high season and on weekends.
- Wear comfortable, non‑slip footwear; the 200‑metre cobbled ramp and final staircases are gently sloped but can feel tiring and occasionally slick in wet weather.
- Check the current exhibition in the Library Hall before you go; the included shows and occasional concerts or talks can easily extend your visit.
- If you want skyline photos, aim for a clear day with late‑afternoon light or sunset for warm tones on the city’s spires and rooftops.
- Note that there is no elevator; visitors with limited mobility may prefer to enjoy the lower levels and Library Hall rather than attempting the full ascent.

Getting There
-
Metro from central Copenhagen hubs
From major hubs such as Nørreport or Kongens Nytorv, take the M1, M2, M3 or M4 metro to Nørreport if you are not already there; trains run every few minutes and a single zone ticket costs roughly 20–30 DKK. From Nørreport Station, it is an easy 5–10 minute urban walk through level, paved streets to the Round Tower, suitable for most visitors and pushchairs, though the tower itself has no elevator to the top.
-
City bus through the historic centre
Several inner‑city bus lines stop near Nørreport and other central points within a 5–10 minute walk of the Round Tower. Journeys within the central zones usually take 10–20 minutes depending on traffic and cost around 20–30 DKK with the same tickets used for metro and trains. Buses are low‑floor and generally accessible, making them a practical option if you prefer to minimise walking before tackling the tower’s internal ramp.
-
Bicycle within central Copenhagen
Copenhagen’s dense network of bike lanes makes cycling to the Round Tower straightforward from most central districts in about 10–20 minutes. You can rent a city bike or standard bicycle from numerous providers, with typical prices from around 80–150 DKK for a day. Bicycle parking is available on nearby streets, but you will need to lock your bike outside and continue on foot into the pedestrianised area around the entrance.
-
On foot from the old town and waterfront
If you are already exploring the old town, Strøget shopping street or the inner harbour area, allow 10–25 minutes to walk to the Round Tower along largely flat, paved pedestrian routes. Walking is free and lets you combine the visit with nearby sights such as Rosenborg Castle or the cathedral. Surfaces are suitable for strollers, though cobblestones in some streets and within the tower make very small wheels less comfortable.

Discover more about The Round Tower
A royal tower with its eyes on the stars
The Round Tower, or Rundetaarn, was completed in 1642 as part of King Christian IV’s ambitious Trinitatis Complex, combining an observatory, university library and church in one integrated ensemble. Conceived as a “castle of the stars” for scholars in Copenhagen, the tower quickly became a symbol of Denmark’s scientific curiosity and royal power. Its sturdy brick cylinder still anchors Købmagergade, a busy pedestrian street, but step inside and you are entering a purpose‑built scientific instrument as much as a monument. High above the tower sits one of Europe’s oldest functioning observatories. For centuries, astronomers climbed up here to chart the heavens, making measurements that would help place Denmark on the scientific map. Today, the observatory retains its historic telescope and timbered interior, and in the darker months it again opens for stargazing evenings, connecting modern visitors with the same night sky that early scientists once studied.The spiral ramp that winds through history
Instead of a staircase, the Round Tower is famous for its wide, whitewashed spiral ramp that coils 7½ times around the hollow core. This ingenious design allowed horses and carts to climb up with delicate instruments and books when the tower served the university. Now the gently sloping, cobbled ramp leads visitors upwards in a slow reveal: narrow windows, thick brick walls and occasional alcoves mark your progress as daylight shifts with every turn. Along the way, you pass small landings and niches, once used as resting spots and storage corners, now favourite hideaways for children or quiet places to pause. About two‑thirds of the way up, a glass floor spans the central shaft, letting you peer down into the tower’s hollow interior. It’s a brief thrill that also reminds you how unusual this structure is, designed from the start as a vertical corridor of knowledge.The Library Hall: from dusty volumes to vibrant culture
Roughly halfway up the tower, on the level above Trinitatis Church, you step into the long, vaulted Library Hall. In the 17th century this timber‑roofed space held the entire book collection of the University of Copenhagen, lining the walls from floor to ceiling. Scholars studied under the beams here until the mid‑19th century, when the library moved to new premises and the hall gradually found a new purpose. Today the Library Hall is the tower’s cultural heart. Rotating exhibitions span contemporary art, photography, design, science themes and historical displays, often with a Nordic twist. Concerts, talks, festivals and family workshops bring the old room to life in the evenings. At one end you find a small shop and café counter, where books, prints and Danish design objects echo the tower’s blend of learning and creativity.Skyline views and Copenhagen’s changing face
At the top, a short wooden staircase and a tighter stone stair bring you out onto the open viewing platform wrapped around the observatory dome. From here, the city unfurls in every direction: copper spires, terracotta roofs and church towers punctuate the skyline, while new harbour developments and bridges glint further away. On clear days you can trace the line of the Øresund and even glimpse Sweden across the water. The platform’s low railings and compass points invite you to match landmarks with names: the towers of Copenhagen Cathedral and the old stock exchange, Rosenborg’s turrets set in its gardens, and the distant dome of the Marble Church. In the wind you can almost hear the layers of the city’s past, from medieval merchants to modern cyclists below. During restoration periods the observatory dome itself may be closed, but the tower strives to keep this outdoor panorama accessible whenever possible.Practical character and the rhythm of a visit
Despite its historic pedigree, the Round Tower is a straightforward, urban experience. Entry is via a small ticket hall on Købmagergade, and visits follow a simple flow up the ramp, through the Library Hall, then onward to the viewing platform before descending the same way. There is no lift, and the last part involves stairs, so the very top is not accessible to all, though the ramp and Library Hall can be reached with care. Inside, the atmosphere shifts with the time of day and season. Mornings outside school holidays can feel almost contemplative, with soft light in the ramp and space to absorb details in the brickwork and timber. Afternoons and early evenings are livelier, especially when exhibitions or events are taking place. Because the tower stands in the compact historic centre, it fits easily into a day of museum‑hopping, shopping streets and nearby royal sites.Stories, details and small discoveries
The Round Tower rewards slow looking. Inscriptions and royal monograms on the exterior recall Christian IV’s hand in its creation. Inside, worn cobbles on the ramp record centuries of footsteps, hooves and cart wheels. The proximity to Trinitatis Church below adds a subtle sacred layer: at certain points you can sense, just beneath your feet, the volume of the church nave. Scattered details bring the tower’s human stories to the surface: an old astronomer’s toilet tucked into the wall, the hollow shaft spanned by that daring glass floor, and the way light slices through the small windows at different times of day. Seasonal exhibitions and special programmes themed around light, astronomy or Danish culture ensure that no two visits are exactly the same. Yet the core experience remains constant: a gradual ascent from bustling street to quiet sky, within a cylinder of brick that has watched Copenhagen change for nearly four centuries.Iconic landmarks you can’t miss
