The Bistumshöhe observation tower at Lake Cospuden planned by Werner Sobek was part of the EXPO 2000 project “Landscape Use and Management” in the Leipzig area. The tower is 35 m high and has a circular ground plan with a floor area of 113 m². Its diameter tapers from 12 to 7 m towards the top. The two platforms are reached via an internal, spiral steel staircase 1.25 m wide. They are made of a load-bearing tubular steel construction on which gratings are laid as a walking surface.
Reduced to the Essential
The deliberately simple design, reduced to the essentials, makes the observation tower a striking landmark in the landscape, visible from afar. This minimalism is also reflected in the choice of materials: the material wood (Siberian larch) allows for a transparent, light construction that is nevertheless very robust and resistant.
The footbridges at Lake Cospuden connect various facilities in the new park, which was built on a former open-cast lignite mine. The bridges were also built within the EXPO project.
