Bismarck Tower, Observation monument in Memmingen, Germany.

Bismarck Tower in Memmingen is a stone monument that rises 18 meters high and features an observation platform at its top. From this elevated position, visitors can look out over the surrounding city and landscape.

The tower was built in 1904 by the Memmingen beautification association to plans by city architect Peter Lang, as an 18-metre observation tower with an annex and battlements. After nearly four years it was rededicated as a Bismarck Tower by admirers of Otto von Bismarck, who added a coloured Bismarck coat of arms by stonemason Georg Pöppel and a Bismarck relief by sculptor Gustav Adolf Daumiller, cast by Christoph Lenz of Nuremberg, at a cost of 1,100 marks. The tower was renovated in 2000 and damaged by arson on 28 July 2011.

Four inscriptions were once mounted below the observation platform, including "Wir Deutsche fürchten Gott, sonst nichts auf der Welt" and "Die nationale Einigung der Deutschen war der Leitstern meiner Laufbahn". The Bismarck motto IN TRINITATE ROBUR beneath the coat of arms is no longer present, and the coat of arms itself has been painted over in white.

The tower stands on the Hühnerberg above Memmingen, reached on foot via paths on the hill; there is no lift. The entrance was bricked up and the interior was damaged by a fire on 28 July 2011, so the climb to the platform should not be assumed to be open. Sturdy footwear helps on the hill paths.

It is one of around 240 similar towers built throughout the German Empire, yet only a few remain fully intact and publicly accessible today. This large number shows how widespread this form of commemoration was during that period.
