Nature Park to the south of Stuttgart has been one tourist attraction richer since summer 2018. On the top of the Stellberg Hill at 580 m above sea level stands an elegant, 35 m high viewing tower. Visitors can enjoy an open 360° panoramic view over the Black Forest. The tower consists of eight 10 m long masts made from larch glued laminated timber. The masts fan out upwards and carry three viewing platforms at heights of 10, 20 and 30 m above the ground. A double helix in the form of two steel staircases with cantilevering steps winds around the masts. The client wanted an open structure that harmoniously connects with the surrounding forest.
