A military structure identified by the designation 'Cr 36' is located near the town of Plounévez-Quintin in the Côtes-d'Armor department of Brittany, France. The precise nature, historical context, and original function of this site are not confirmed by the available information. The region of Brittany has a significant military history, including fortifications from various periods, but no specific details linking this particular location to a known historical event, construction program, or military unit are provided in the source material. Current conditions and any potential public access status are unknown.
Without corroborating historical records, archaeological surveys, or official heritage listings, the site's classification—whether as a bunker, shelter, ammunition storage, or another type of military installation—remains unverified. The coordinates place it in a rural, forested area typical of many discreet military or defensive structures built across France during the 20th century, but this is a general geographical observation, not a confirmed fact about this specific site.
