This bunker is located near the village of Paberžė in central Lithuania, within the Šermukšniai forest area. It was constructed in 1944 by and for the Lithuanian partisan group known as the "Šernai" (Boars), which operated in the region during and after the Second World War. The structure served as a clandestine hideout and base of operations for anti-Soviet resistance fighters.
Architecturally, it is a simple dugout shelter designed for temporary occupation and concealment. Historical records indicate that it could accommodate approximately 13 partisans at a time, though it was not used for permanent, continuous habitation. The bunker's location in a forested area provided essential cover and camouflage from patrols.
The site remained in use by partisans until around 1953, during the early Cold War period of Soviet occupation. Today, the bunker exists as a historical monument and a place of remembrance for the Lithuanian freedom struggle. It is accessible via a trail and is marked for visitors interested in military heritage and the history of World War II resistance movements in the Baltic states.
Its significance lies in its representation of the forest brother phenomenon—the network of partisan bunkers and camps that formed the backbone of the armed resistance against Soviet re-occupation in Lithuania from 1944 to 1953.
