Bismarck Tower, Memorial tower on Mount Saint-Quentin, Le Ban-Saint-Martin, France

Bismarck Tower is a 13.5-metre limestone memorial on the southeastern slope of Mont Saint-Quentin in Le Ban-Saint-Martin, not at the summit. It stands on a four-step base with a 1.5-metre socle, four pale Jaumont limestone pillars with rounded edges, and a projecting top. A sandstone relief of Bismarck on the town-facing side is pitted by bullet holes, and the pillars carry graffiti.

A committee formed in Metz in September 1899 launched a subscription for a tower to Otto von Bismarck, chancellor of the German Reich from 1871 to 1890. The site on the Mont Saint-Quentin slope was chosen so the tower would be visible from Metz, and a 12-metre wooden mock-up was built to check this. The limestone tower, 13.5 metres high, was inaugurated on 1 April 1902, Bismarck's birthday, with the fire lit at 20:00. After 1918 the Bismarck medallion was riddled with bullets.

The tower's name recalls Otto von Bismarck, chancellor of the German Empire from 1871 to 1890. The Metzer Zeitung, which had launched the subscription, proposed renaming Mont Saint-Quentin "Bismarck Höhe", but the idea was rejected. The sandstone medallion of Bismarck on the town-facing side was riddled with bullets after 1918.

The site is reachable by hiking trail from Plappeville, with the route passing through forest and over hills. It is best to wear sturdy shoes and allow time for both the climb and descent since the paths are uneven.

The tower is one of about forty built to Wilhelm Kreis's Götterdämmerung design, and its sandstone Bismarck medallion was riddled with bullets after 1918. The Metzer Zeitung proposed renaming Mont Saint-Quentin 'Bismarck Höhe', but the idea was rejected.
