The model of the "German Stadium" was built in 1937 in the Hirschbachtal near Oberklausen (am Stockbühl) under the guidance of the architect Albert Speer.
Over 400 workers, mostly forced laborers from the Flossenbürg concentration camp, were busy day and night for 18 months building the stands in the forest. The trees were felled, foundations and retaining walls were concreted.
When the Second World War broke out, construction work in Oberklausen was also stopped. Only the SS guards stayed and guarded the building.
In the last days of the war in April 1945, the area around the experimental bleachers was fiercely contested, as some men of the SS offered bitter resistance to the Americans.
The nearby village of Achtel was almost completely destroyed.
The American US military government ordered the wooden structures to be demolished. The long timbers of the stands from the Bavarian Forest were used for the reconstruction of the destroyed village Achtel.
The Stadionberg was forgotten for decades and nature took back what was once taken from it. Pine trees, bushes and many other plants overgrown the concrete base on the slope.
In 1999 the remains of the building were placed under monument protection.
