Getting There

  • Walking

    From the central rail station area, the Round Tower can be reached by a pleasant 15–25 minute walk through Copenhagen’s lively Strøget pedestrian zone. As you approach the historic core, the tower’s distinctive dome appears above the rooftops near the university quarter. The entrance is easily found beside busy shops and cafés, with step-free street access.

  • Public Transport

    Multiple city buses and the metro connect central transport hubs with the Round Tower area. Disembark at Nørreport Station (serving metro and regional trains) and follow the flow of shoppers and sightseers—it's about a 5–10 minute walk from there, passing major city landmarks. A single adult public transport ticket typically costs DKK 24 for inner-city journeys.

  • Taxi

    A taxi from Copenhagen Central Station or the city harbor brings you directly to the busy square behind the Round Tower entrance. Allow 5–12 minutes depending on traffic; expect fares of DKK 70–110 within central districts.

  • Driving/Parking

    Parking in central Copenhagen is limited and often busy; municipal paid parking is available in the surrounding streets and underground garages nearby, usually DKK 40–55/hour. Expect a short walk from your car through a bustling pedestrian area—consider leaving the car behind if possible.

Discover more about The Round Tower

The Round Tower, or Rundetårn, is one of Copenhagen’s most enduring icons—a testament to Denmark’s golden age of science and its centuries-long affection for architectural whimsy. Commissioned by King Christian IV in the early 17th century, the tower was completed in 1642 as part of the Trinitatis Complex, which housed an observatory, a university church, and an academic library. Its primary function was to serve the burgeoning field of astronomy at a time when Denmark aspired to be at the forefront of scientific study. The tower’s most celebrated feature is its wide, spiraling ramp that coils 7.5 times from street level to the observation platform some 34 meters above the cobbles. This unique ramp was ingeniously designed so horses—and even chariots—could carry equipment and aristocratic visitors all the way to the top, a rare architectural curiosity in Europe. At its summit, visitors are greeted with sweeping, unobstructed vistas of Copenhagen’s rooftops, spires, and hidden courtyards, making the Round Tower a photographer’s favorite and a moment of orientation for any city wanderer. Besides the observatory (still in use for stargazing events), the tower hosts rotating exhibitions, concerts, and children’s activities within its atmospheric interiors. The original library now showcases contemporary art and holds engaging cultural programs. The Round Tower is more than a relic—it is a living cultural space, frequented by locals and visitors year-round. Its city-center location makes it a perfect pivot for exploring the heart of Copenhagen, whether you are drawn here by the promise of views, the echo of historic footsteps, or the playful challenge of ascending its ramp. With its blend of science, history, and lively present-day happenings, the Round Tower stands as an unmissable highlight for any traveler to Zealand.
