A military bunker located near the village of A-140 in Slovakia, situated in the Danube Lowland region. This structure is part of Slovakia's extensive network of fortifications dating from the interwar period and World War II era. The region around A-140 contains numerous defensive positions built as part of Czechoslovakia's border fortifications before the country's occupation.
These bunkers were designed to defend against potential German and Hungarian aggression during the politically turbulent 1930s. The specific designation 'LIII/216/A-140' follows the standard Czechoslovak military nomenclature system used for identifying individual fortification positions along the border defenses.
