This over 40 meter high belvedere is situated at the highest point of the Killesberg Park and offers a terrific view over the city of Stuttgart and its surroundings. Two light spiral staircases, with each 174 steps, connect four platforms with levels of 8, 16, 24 and 31 meter. To separate the traffic streams of people one leads the visitors up and one brings them down. The structure consists of a prestressed cable-net. 48 cables with a diameter of 18 mm are spun around the mast and platforms. At 34 metre the cable net is connected to a compression ring and at the bottom at a ring basis. Because the mast pushes the ring and connected net up, the net becomes prestressed and in the cables only the pulling strength is working. Thanks to that trick the cables could be formed so very thin! On a windy day, you shouldn't be afraid of heights, it can be exciting and shaky...
