Large wind tunnel in Adlershof, Architectural heritage monument in Adlershof, Germany

The Large Wind Tunnel is a tubular structure with a diameter of 8.5 to 12 metres, built in reinforced concrete using the Zeiss-Dywidag shell method with walls only 8 cm thick. Inside, the airflow was directed at aircraft parts in a measuring chamber to record their drag. It stands in the Aerodynamic Park in Berlin-Adlershof as a listed monument of the former Deutsche Versuchsanstalt für Luftfahrt.

Built between 1932 and 1934 by Dyckerhoff und Widmann & Beton- und Monierbau AG, this facility served the Deutsche Versuchsanstalt für Luftfahrt until World War II ended.

The tunnel's unusual concrete shell made it a film set: scenes of Æon Flux (2005), set 400 years in the future, were shot inside the tube, and Hanna (2011) followed. Near the entrance a Russian graffiti from 1945 reads "Geprüft – keine Minen!" ("Checked – no mines!").

The tunnel is a protected monument and no longer used for research or teaching. Because its shell is only 8 cm thick and has limited load capacity, it opens rarely and only to small groups; visits must be arranged in advance.

Beside the entrance, a Russian graffito from 1945 can still be read: "Geprüft – keine Minen!" ("Checked – no mines!"). The tunnel's unusual architecture later made it a film set, notably for Æon Flux (2005), set 400 years in the future, with many scenes shot inside the tube.
