Uni-Center

Completed in 1973, the Uni-Center in Cologne's Sülz district is one of the largest residential buildings in Europe and is known for its Y-shaped architecture. Designed by Cologne architect Werner Ingendaay, the building consists of three color-coded wings and a central tower that rises 134 meters (440 feet) and shapes the skyline. The facade is divided into orange, green, and yellow sections to help residents and visitors find their way around. Inside, 968 residential units are spread across the complex, including a large student residence run by the Cologne student services organization (Kölner Studierendenwerk) as well as privately owned apartments. The lower floors house shops, restaurants, and a parking garage. The building is not only an architectural landmark but also historically significant: it served as a filming location for the movie The Lost Honor of Katharina Blum and was the scene of police investigations during the German Autumn.
