The Killesberg Tower is a 40.4-meter high observation tower located in the Killesberg Park in Stuttgart, Germany. According to the write-up posted, it was originally planned for the 1993 World Horticultural Exposition, however, it was finally erected in 2001.

The four observation decks at 8, 16, 24, and 31 meters are hinged to the main mast and at their circumference connected to the net by press fittings. The two spiral staircases, one for ascending and another for descending, are suspended only by the steel cable net.

Significant design elements of the tower are the central main mast whose heel is hinged by a steel ball to the central foundation, and the steel cable net of triangular meshes. The net is tensioned between a circular concrete foundation and a pressure ring at an altitude of 33.5 meters which in turn is suspended from the mast head by cables.

All cables and fittings are galvanized. In addition, all steel construction elements received a double paint coat. The hollow sections, i.e., the mast and the stair tubes, are galvanized on both their inner and outer surfaces.

Access to the park and the tower is free of charge. For the tower, a voluntary contribution is suggested. Opening hours are from 7 a.m. until nightfall. On a clear day, there would be a very nice view of Stuttgart from the top observation deck (31 meters). Unfortunately, it was cloudy/sprinkling when we visited. Even then, there was a very nice view of the park. If you have acrophobia or fear of heights, I'd suggest you'd skip climbing this one and look from below.
