OB 15,5cm Geschütz (zerst.)

{ "description": "A destroyed German World War II artillery bunker, designated 'OB 15,5cm Geschütz', located near the Normandy coast in northern France. The designation indicates it was built to house a 15.5 cm (approximately 6.1 inch) naval or coastal artillery gun as part of the Atlantic Wall fortifications. These structures were standard components of Germany's coastal defense system in occupied Western Europe during the war.\n\n The bunker's remains are situated at coordinates within the Calvados department, an area that saw significant military construction and later combat during the 1944 Normandy landings. The 'zerst.' suffix in the name confirms the structure was destroyed, likely during the Allied invasion or subsequent clearing operations. Such Regelbau (standardized construction) bunkers were designed for long-range fire support against Allied naval vessels and landing craft.\n\n No direct association with France's post-war nuclear weapons program, as detailed in the provided search results, can be established for this specific WWII-era site. The location's historical significance is confined to its role in the German coastal artillery network of 1943–1944.", "specs": { "build_year": 1943, "function": "artillery bunker", "armament": "15.5 cm gun", "type
