Moschee Wünsdorf, Wooden mosque in Wünsdorf, Germany

Moschee Wünsdorf was a timber mosque with double board cladding on massive foundation walls, built in five weeks in 1915 by the Charlottenburg firm Stiebitz und Köpchen. Its polygonal prayer hall carried a central dome 12 metres across, set above a surrounding gallery with a lean-to roof; the minaret stood 23 metres tall. To the south were an antechamber, preacher's room and corpse-washing room, to the north a square courtyard with a fountain and an adjoining bathhouse.

The mosque was approved by the War Ministry in February 1915 and built in five weeks by the Charlottenburg firm Stiebitz und Köpchen for 45,000 gold marks. It opened on 13 July 1915, at the start of Ramadan, with Turkish diplomat Mahmut Muhtar Pasha present. After the war, 90 Muslims continued to use it until it was closed in 1924 as unsafe and demolished in 1925/26.

The mosque was inaugurated on 13 July 1915, the start of Ramadan, in the presence of the Turkish diplomat Mahmut Muhtar Pasha. Prisoners from the Halbmondlager came from India, North Africa and Syria, while the neighbouring Weinberglager held men from French colonies and Tatars. After the war about 90 Muslims stayed in two nearby barracks and, with official permission, continued religious life in Wünsdorf.

The mosque stood inside the Halbmondlager, a First World War prisoner-of-war camp in Wünsdorf south of Berlin. Nothing of the wooden building survives; the site is now a parking area and a container housing complex. A memorial information board, the street name Moscheestraße and some soldiers' graves recall it. Excavations in 2015 examined the southern annex with the minaret.

The 2015 excavation by the Brandenburg State Office for Monument Preservation and the Free University of Berlin focused on the southern annex with the minaret, since the main domed hall lay beneath today's parking lot. The prayer room's brick foundations and stone floor slabs had been deliberately removed after demolition, probably for reuse; what remained was rubble, iron ties, fragments of chandeliers and coloured glass from the dome windows.
