A military bunker located near Wezet (Wesel), in the province of Liège, Belgium, this structure is identified by the designation B/ON-2273 and associated with the Belgian Wz 35 fortification system. Built during the interwar period as part of Belgium’s defensive preparations ahead of World War II, the bunker forms part of a network of fortified positions designed to slow potential invasions from the east, particularly along the Meuse River corridor.
The Wz 35 (Werk 1935) series was a standardized Belgian military construction program, featuring reinforced concrete bunkers with machine gun embrasures and limited artillery support. Unlike the more elaborate French Maginot Line or German Siegfried Line, the Wz 35 bunkers were smaller, cost-effective, and intended for infantry defense. This specific site, B/ON-2273, is typical of these low-profile, locally constructed positions, often sited to provide overlapping fields of fire with neighboring bunkers.
Located in a rural area near the Dutch border, the bunker remains largely intact but abandoned. Its entrance is partially obstructed, and vegetation has encroached on the structure, making it a site of interest for urban explorers (urbex) and military history enthusiasts. No evidence suggests it was ever used as a command post, ammunition depot, or nuclear shelter. Its primary function was as a defensive infantry strongpoint.
The bunker’s designation and location confirm its origin in Belgium’s pre-WWII military planning. It is not related to German Regelbau designs, nor does it belong to the Atlantic Wall. Its preservation offers a tangible link to Belgium’s interwar fortification efforts and the broader European arms race of the 1930s.
