Bismarck Tower, Memorial tower in Kray district, Essen, Germany.

Bismarck Tower in Essen is a 16.75-metre fire column of basalt lava on the Mechtenberg in the Kray district. Its front and rear faces each carry the name BISMARCK in gilded capital letters; a wrought-iron Bismarck coat of arms on the north side has been gone since the 1990s. The 1.8-metre fire bowl that once crowned it is also lost.

The structure was built in 1900 through public donations to honor Otto von Bismarck, with Emil Kirdorf and the Bismarck Association leading the initiative. This memorial form emerged during an era when such monuments became common across German cities.

The tower bears the name BISMARCK in gilded capital letters on its front and rear faces. A forged Bismarck coat of arms on the north side has not existed since the 1990s. Every Good Friday, the Catholic parish of Mariä Himmelfahrt in Gelsenkirchen-Rotthausen holds a Stations of the Cross procession from the Düppeler Kirche to the tower.

The monument sits on Mechtenberg hill in Essen's Kray district with parking available for visitors exploring the surrounding landscape park. The hill is easy to reach and suits a casual walk with views of the area.

A fire bowl once sat at the summit and was operated by a pressure pump system until its removal during World War II due to material shortages. This burning top was once a notable nighttime landmark on the hill.
