B/ON-0856 Bunker KW Line VB53 is a World War II-era military bunker located in Vlaams-Brabant, Belgium. It forms part of the KW Line, a defensive fortification constructed by the Belgian Army in 1939-1940 as a last-ditch barrier against potential German invasion. The KW Line stretched from Koningshooikt to Wavre, combining anti-tank obstacles, trenches, and reinforced concrete bunkers like this one.
Situated near the village of Sint-Agatha-Rode, this bunker exemplifies the rapid militarization of Belgium in the tense pre-war period.
