Cologne's green lung consists of approximately 800 hectares, almost half of it in forest. Wide open spaces, like the Decksteiner Weiher, or huge lawns, give you free sight, let you breathe deep and make you forget that you are still in a big city.
This green area was built up in the twenties of the last century on the initiative of Konrad Adenauer, the later chancellor and at that time Cologne's mayor. The forest consists of a species-rich mixture of deciduous trees and types of coniferous woodland.
Apart from the local recreation value, the green belt offers protection from the emissions of the nearby motorway, too. Dust and pollutants in the urban air are partly bonded by means of the green belt's natural filter effect. though this space alone could only clean the polluted air to a small extent. Mainly the emissions need to be reduced to save our atmosphere.
