KölnTrianglePanorama

The KölnTriangle is a striking high-rise on the east bank of the Rhine in Cologne, completed in 2006 to designs by the architecture firm Gatermann+Schossig. Standing more than 100 meters tall with 29 floors, the building stands out for its triangular floor plan with curved edges. It was planned as an investment property by the Rheinische Versorgungskassen and is connected to the neighboring LVR-Horionhaus by two gateways that form a publicly accessible courtyard. During construction, the building's height became a political issue that even contributed to the debate over the World Heritage status of Cologne Cathedral and ultimately led to a revision of the high-rise concept for the Deutz district.

Visitors can enjoy a wide view over the city from the fully glazed observation deck, which officially opened on September 2, 2006. More than 600,000 guests have taken in this perspective to date, and the deck is also used for television productions and events such as the Cologne Lights. The ground floor and upper levels house a range of facilities, including a restaurant, medical practices, and office space rented by city authorities and other companies.

The architectural concept is complemented by public art. New York artist Rainer Gross created a typographic mural in the entrance area that tells the history of the Deutz district. In front of the building stands his ten-meter-high water installation Deutz Twins, which forms a reflective unit with a long pool and looks especially impressive when lit up in the evening. These elements underscore the modern design of the building, which received an award in 2006 for its innovative glass facade.
