FA Richthaus is a military bunker located in northern France, near the town of Écurie. This structure is part of the extensive network of fortifications built along the French coast during the Second World War as part of the Atlantic Wall defenses. The bunker's designation 'FA' indicates it was likely a fire control or artillery observation post, designed to coordinate coastal artillery fire and monitor enemy movements.
Situated in the Pas-de-Calais region, this area saw significant military activity during both World Wars due to its strategic position facing the English Channel.
