Situated on the Rhine River in the centre of the Rhine-Rhur region, charming Cologne is the beating heart of the beautiful Rhineland. Originally founded over 2,000 years ago by the Ubii tribe, Cologne was once the largest city in the Holy Roman Empire and served as a major trade route throughout the Middle Ages. In recent years the city has been extensively rebuilt and restructured and is now one of the most important historical and cultural centres in Europe.
