Friedenswarte Brandenburg, Observation tower in Brandenburg an der Havel, Germany

The Friedenswarte is an observation tower in Brandenburg an der Havel with two separate staircases serving ten viewing platforms arranged at different heights. The structure provides both enclosed and open-air platforms for panoramic views across the city and surrounding areas.

The tower was built as the Bismarckwarte on the Marienberg, initiated by toy manufacturer Ernst Paul Lehmann with plans by Bruno Möhring; the foundation stone was laid on 1 April 1905 and it opened on 1 April 1908. It was renamed Friedenswarte by a city council decision of 28 August 1958, and the Bismarck bust niche was covered with a peace-dove relief by Karl Mertens. The tower was demolished on 22 March 1974 and replaced by the present structure, designed by Günter Franke and Wolfgang Schoppe and finished on 7 October 1974.

The tower's name changed on 31 August 1958, when the city council renamed the Bismarckwarte as Friedenswarte. At the same time the niche holding Hugo Lederer's bust of Bismarck was walled up and covered with a peace-dove relief by sculptor Karl Mertens. The inscription above the old entrance read "GETREUE / BRANDENBURGER / IHREM BISMARCK".

The climb involves about 360 steps distributed across two separate staircases, with distinct routes for going up and coming down. Visitors can pause at various platforms along the way and are not required to reach the highest point if they prefer shorter views.

The structure incorporates modern materials such as chrome-nickel steel and glass in its design, setting it apart from traditional observation towers. These contemporary elements define its appearance and reflect the deliberate choice to build anew rather than simply restore the original.
