FA Kompressor is a military bunker located in northern France, near the town of Étaples. This structure is part of France's Cold War-era defensive infrastructure, built during a period of heightened nuclear tensions. The bunker's name suggests it may have served as a compressor station or air filtration facility, typical of hardened military installations designed to protect personnel from chemical, biological, or nuclear threats.
Its location in the Pas-de-Calais region places it within an area historically significant for military fortifications, from medieval castles to World War II defenses.
