The B/ON-1202 Bunker Luchtafweergeschut Oostende is a World War II-era anti-aircraft bunker located in the coastal city of Oostende, West Flanders, Belgium. Built during the German occupation, this fortified structure formed part of the Atlantic Wall coastal defenses designed to protect against Allied air raids and naval bombardments. Its strategic position near the North Sea made it a key component in the German Luftwaffe's air defense network along the Belgian coast.
The bunker's design reflects typical Regelbau (standardized) construction methods used by the German military during the war, optimized for housing anti-aircraft artillery and providing protection for gun crews. Situated in a region heavily fortified during WWII, it stands as a reminder of the extensive military infrastructure developed along Europe's western seaboard. Today, the site is of interest to military history enthusiasts and urban explorers studying the remnants of the Atlantic Wall.
