The tower in the Höhenpark Killesberg guarantees not only wide visibility when the weather is nice; people who struggle with vertigo can also treat their fear of heights here. The architectural masterpiece comes from the Stuttgart civil engineer icon Jörg Schlaich, who constructed a mast braced with steel cable nets with four viewing platforms—the top one 100 feet high—and a spiral staircase. For engineers a wonderful object of study for the construction of buildings; but it is also no less exciting for laymen to work their way up the stairs, which always fluctuate slightly, to surrender to the changed views platform by platform and finally to wobble down again. The history of the tower’s construction is also unique—you can read it on the website.
