The 58m high tower that topped off the main station in 1927 offers excellent views over the centre as well as the massive Stuttgart 21 development project behind the station - an exhibition documents this inside the tower (open 10:00-18:00, Thu 10:00-21:00, closed Mon). The café with great views is an alternative to the rather characterless food and drink possibilities at platform level. Contact TurmForum for tours of the tower.
