The Tannenberg Memorial, also known as Tannenberg Nationaldenkmal, was a monumental structure built between 1924 and 1927 in East Prussia to commemorate World War I battles and the medieval Battle of Tannenberg.
The monument was designed by architects Johannes and Walter Krüger from Berlin, featuring a fortress-like octagonal design.
Under the Nazis, the memorial was transformed into Reichsehrenmal Tannenberg and served as a site of national mourning for Hindenburg, who was buried there.
In January 1945, as Soviet forces advanced, Wehrmacht engineers demolished parts of the memorial to prevent its capture, and it was further dismantled in the years that followed.
Today, almost no visible remains exist at the site, with only fragments and traces left in the landscape.
The memorial is studied as a case of 'absent monuments' reflecting on memory, forgetting, and the complexities of commemorating problematic historical figures.
