About KölnTriangle
The KölnTriangle is a 103-meter, 29-storey office building in Deutz, on the right bank of the Reno. It was completed in 2006 and has a triangular floor plan with curved sides, hence the name. During construction, the debate over tall buildings near the cathedral even led UNESCO to place the Dom on the list of World Heritage in Danger for a few years.
On the top floor there is a roughly 400-square-meter glass-enclosed platform with its own entrance. From there you can see the cathedral head-on, the Hohenzollernbrücke, the old town, Groß St. Martin and the Museum Ludwig.
In clear weather the view reaches Düsseldorf to the north and the Siebengebirge hills to the south. The platform closes in case of storms or strong winds.
Before you go
Practical information
Cidade Turismo reviews its information regularly, but something may have changed. Check with the place before planning your trip.
How much time to set aside
30 to 45 minutes.
Best time
In the late afternoon, to see the cathedral in the light of the setting sun, or at night with the city illuminated. The platform usually stays open later on Fridays and Saturdays from May to September; check opening times.
How to get there
It's about a 10-minute walk from the cathedral, crossing the Hohenzollernbrücke. The nearest stations are Köln Messe/Deutz and Deutzer Freiheit.
Tip
Combine the bridge crossing and the Rheinpark in the same late-afternoon walk.

Frequently asked questions about KölnTriangle
Is the platform open or enclosed?
It is enclosed with glass, allowing visits even in cold weather or light rain. In a storm it closes.
Is a reservation necessary?
Usually it's not necessary; tickets are bought on site. Check opening hours before you go.
Is the view better than the cathedral tower's?
They are different. From the tower you can't see the cathedral itself; from the KölnTriangle it appears whole, head-on, with the bridge.
