The metropolitan area encompasses over 405 square kilometers. The city's highest point is 118 meters above sea level (the Monte Troodelöh) and its lowest point is 37.5 meters above sea level (the Worringer Bruch).The city of Cologne lies within the larger area of the Cologne Lowland, a cone-shaped area of southeastern Westphalia that lies between Bonn, Aix la Chapelle and Düsseldorf.In the 1980s and 1990s Cologne's economy prospered for two main reasons. Firstly, a growth in the number of media companies, both in the private and public sectors; they are especially catered for in the newly-developed Media Park, which creates a strongly visual focal point in the Cologne town center and includes the KölnTurm, one of Cologne's most prominent high-rise buildings. Secondly, a permanent improvement of the diverse traffic infrastructure made Cologne one of the most easily accessible metropolitan areas in Central Europe.
