The Fuchsbau (German: Foxhole) is a military bunker system, located south of the town of Fürstenwalde, Brandenburg, about 55 km (34 mi) east of Berlin.

The bunker served as Zentraler Gefechtsstand 14 (ZGS-14) ("Central Component Headquarters 14") of the East German Air Force Kommando LSK/LV from 1965 until 1990, when the compound became the headquarters of Bundeswehr's 5.

The facilities were shut down in December 1994, when the 5.

Luftwaffendivision was disbanded.

[1][2] With 9,000 m2 (97,000 sq ft) of floor space, 650 m (2,130 ft) of corridors, and up to 350 personnel, it was one of the largest bunkers in the German Democratic Republic (GDR).
