The Bismarck tower in Freiburg im Breisgau belongs to a series of towers that were build in honor of Otto von Bismarck, the first German chancellor. It is located on the Schlossberg. It is 12.6 m (41 ft) tall and has a square base (5.8x5.8 m or 19x19 ft). The top of the tower can only be reached by climbing a ladder. Because of this it can not be used as an oberservation deck.
