A military bunker located near Plouay in the Morbihan department of Brittany, France. The site's designation 'FA Gebäude' incorporates German terminology ('Gebäude' meaning building), which may suggest construction during the German occupation of France in World War II, though this connection is not confirmed by available sources. The region of Brittany saw significant German fortification efforts as part of the Atlantic Wall coastal defenses, particularly along the Atlantic coastline.
The precise purpose, construction date, and current condition of this specific structure remain unverified. The location's coordinates place it inland, away from the immediate coastline, which could indicate a support, storage, or command function rather than a primary coastal artillery position. Further archaeological or archival research would be needed to confirm its historical role and period of use.
