The easiest way to reach The Round Tower in Copenhagen is to go to Nørreport Station, then walk about five minutes through Frederiksborggade and Kultorvet to Købmagergade 52A. From the station, do not follow Nørre Voldgade along the transport corridor; locate Frederiksborggade, walk toward Kultorvet, and continue onto Købmagergade.
Nørreport is served by Metro lines M1 and M2, S-trains, regional trains, and buses. If you are coming from Copenhagen Airport, take the M2 toward Vanløse directly to Nørreport. No transfer is required before the final walk.
The Round Tower stands directly in the Købmagergade street frontage rather than behind a forecourt. Look for its curved yellow-and-red wall and entrance portal instead of expecting to see the entire tower from Nørreport.
Leave Nørreport via Frederiksborggade
Nørreport is Copenhagen’s busiest station, with several street-level exits and transport stops spread along Nørre Voldgade. Confirm that you have found Frederiksborggade before beginning the five-minute walk. If Torvehallerne is your actual destination, use the Nørreport Station to Torvehallerne walk toward Israels Plads instead of following this route through Kultorvet.
Frederiksborggade leads from the station area toward Kultorvet. The correct route moves away from the rail and bus corridor rather than following Nørre Voldgade beside it.
Use this street sequence:
| Stage | What to follow | Mistake to avoid |
|---|---|---|
| Nørreport Station | Signs to street level | Starting navigation while still underground |
| Station area | Frederiksborggade toward Kultorvet | Walking east or west along Nørre Voldgade |
| Kultorvet | Continue through the square | Treating the square as the destination |
| Købmagergade | Walk to number 52A | Searching for a separate palace-style entrance |
| The Round Tower | Use the entrance portal on Købmagergade | Walking past the tower while looking at the skyline |
If the first part of the walk keeps you beside buses, station entrances, or heavy traffic, check the street name. You should be moving along Frederiksborggade toward the pedestrian centre.
Continue through Kultorvet onto Købmagergade
Frederiksborggade brings you to Kultorvet, a pedestrian square between Nørreport and The Round Tower. Continue across the square rather than turning into one of the surrounding side streets.
The route then becomes Købmagergade. This is the street named in the tower’s official address:
Købmagergade 52A
1150 Copenhagen K
Købmagergade is a busy pedestrian shopping street, so the presence of shops and foot traffic does not mean that you have missed the attraction. Continue toward number 52A and watch the building frontage.
The Round Tower forms part of the Trinity Complex and stands beside Trinity Church. Its rounded wall rises directly from Købmagergade, and the entrance portal faces the street. You do not need to enter a courtyard or walk around the church to find the ticket office.
Do not navigate by the tower’s roofline
The tower is a major Copenhagen landmark, but nearby buildings can hide much of it during the walk from Nørreport. Searching the skyline at every intersection is less reliable than following the two street names.
Use Frederiksborggade until Kultorvet, then Købmagergade until number 52A. The curved façade becomes obvious only when you are close.
The entrance portal is at street level beneath the tower. If you can see Trinity Church but cannot identify the tower entrance, return to Købmagergade rather than circling the block.
Take M2 directly from Copenhagen Airport to Nørreport
From Copenhagen Airport, follow the Metro signs from Terminal 3 and take the M2 toward Vanløse. Nørreport is on the same line, so no change at Kongens Nytorv or Copenhagen Central Station is required. If Botanical Garden Copenhagen is your actual destination from the airport, follow the Botanical Garden Copenhagen from CPH Airport via Nørreport route and leave Nørreport toward Gothersgade instead.
The complete airport route is:
- Follow the Metro signs from Terminal 3.
- Board the M2 toward Vanløse.
- Get off at Nørreport.
- Reach street level and locate Frederiksborggade.
- Walk through Kultorvet onto Købmagergade.
- Enter The Round Tower at Købmagergade 52A.
Do not add another transfer after Nørreport. For this destination, the last step is walking.
Check the Metro’s live service information before departure, especially if you require a lift. Nørreport normally has two lifts, but temporary outages can change which street-level route is available.
Use an S-train from Copenhagen Central Station
From Copenhagen Central Station, use a northbound S-train that stops at Nørreport, then complete the same five-minute walk. Check the station departure board because several services use this central section.
Walking all the way from Copenhagen Central Station is possible, but it turns a short station-based route into a longer walk through the city centre. Nørreport provides the more direct starting point for finding Frederiksborggade and Købmagergade.
A taxi is usually unnecessary from either station. If weather, luggage, or limited mobility makes a car preferable, use “The Round Tower” or “Købmagergade 52A” as the destination. Because Købmagergade is pedestrian-focused, the final drop-off may be on a nearby accessible street rather than directly outside the entrance.
The five-minute walk ends before a 200-metre spiral ramp
Reaching the entrance from Nørreport and reaching the viewing platform are two different accessibility questions.
Inside the tower, the main route is an ascending spiral ramp approximately 200 metres long. It winds seven and a half times around the tower’s hollow centre. At the end of the ramp, visitors must use a wide wooden staircase followed by a smaller winding stone staircase to reach the viewing platform.
There is no elevator. The official visitor information states that the building is not well suited to wheelchair users because of the incline and the stairs near the top. Wheelchair users can access exhibitions and events in the Library Hall, although the ramp can be difficult for non-electric wheelchairs.
Pushchairs and prams cannot reach the viewing platform. They may be parked just after the ticket booth or near the wooden staircase, but the tower does not accept responsibility for items left there.
Near the top, a traffic light controls movement in both directions through the narrow final section. A short wait at this point does not mean that the platform is closed.
Store suitcases before travelling to Nørreport
Larger luggage and suitcases cannot be brought into The Round Tower, and the attraction does not provide luggage storage.
This restriction is particularly important for visitors arriving directly from Copenhagen Airport or Copenhagen Central Station. Store large bags before taking the final trip to Nørreport rather than reaching Købmagergade and discovering that the suitcase cannot enter.
A small walking distance does not make The Round Tower a suitable stop between an airport arrival and hotel check-in. The restriction applies to the building, not to the route from the station.
Buy ordinary admission at the entrance
Ordinary admission tickets are sold at The Round Tower’s ticket office and cannot be purchased in advance. Online sales are reserved for concerts, talks, and other ticketed events.
The tower has a maximum visitor capacity. During busy periods, a queue or a temporary pause in ticket sales may occur; the official visitor information says waits rarely exceed 20 minutes.
The Round Tower is not included in the Copenhagen Card. Check the current admission price and opening hours on the official website before travelling rather than relying on an older city guide.
The viewing platform is open during the 2026 observatory restoration
As of July 2026, the Observatory is closed while its dome, telescope, roof, and interior are restored. The official project schedule expects the Observatory to reopen in October 2026.
The closure does not normally prevent access to the Spiral Ramp, Library Hall, Bell Loft, or outdoor viewing platform. The platform remains open during the restoration apart from separately announced temporary closures.
Visitors travelling specifically for astronomical observation should check the restoration page before leaving Nørreport. Visitors who want the city view can still use the viewing platform while the Observatory itself is closed.
Restart from Frederiksborggade after a wrong exit
If you leave Nørreport in the wrong direction, return to the station area instead of trying to approach the tower through unrelated side streets.
Rebuild the walk using these confirmed points:
- Nørreport Station
- Frederiksborggade
- Kultorvet
- Købmagergade
- Købmagergade 52A
If you are still walking beside Nørre Voldgade, you have not begun the direct route. If you have reached Kultorvet, continue into Købmagergade. If you are on Købmagergade but cannot see the entrance, use building number 52A and look for the curved tower wall beside Trinity Church.
