Bismarck Tower, Observation tower on Kleperberg hill in Göttingen, Germany.

Bismarck Tower is a 31-metre observation tower on the Kleperberg east of Göttingen, built of limestone rubble with sandstone ornament. Its design by city building officer Heinrich Gerber pairs a hexagonal main tower of 21 metres with an attached round stair tower reaching 31 metres. Two viewing platforms are reached by 180 steps, and the second upper floor holds a Bismarck memorial hall with a bronze bust and donor tablets.

The Göttingen Verschönerungsverein planned a lookout on the Kleperberg in the 1880s; in March 1892 it decided on a monumental tower named after Otto von Bismarck, who had studied law at Göttingen in 1832/33. Bismarck consented in May 1892, and the foundation stone was laid on 28 June 1892. Designed by Stadtbaurat Heinrich Gerber and built by Rathkamp, the tower was inaugurated on 18 June 1896.

The tower sits on Kleperberg, a location that connects the town to the surrounding landscape for local visitors. People use the area today as a hiking destination where they can experience the views across the Göttingen region.

The tower is open to visitors on weekends and public holidays from late March through October, making it accessible during warmer months. Well-maintained walking paths surround the area, allowing you to easily explore the Kleperberg and its forest surroundings.

The memorial hall on the second upper floor holds a bronze bust of Bismarck and originally 30 donor plaques, headed by the plaque of Emperor Wilhelm II. The plaques record the student fraternities, among them Corps Hannovera, Saxonia and Burschenschaft Brunsviga, that helped fund the 43,700-mark construction.
