Carnival as the fifth season, the cathedral, the Rhine, and the love locks on the Hohenzollern Bridge – that’s Cologne. Germany's fourth-largest city likes to present itself as colorful, cosmopolitan and flamboyant. Cologne enjoys the reputation of a multi-layered economic and cultural metropolis with international significance. The numerous colleges and universities, such as the University of Cologne, the Technical University and the German Sport University, also make Cologne the largest education and research location in western Germany.
