The Z2/9/A-140 lom is a military bunker located in the Czech Republic, near the town of Jirkov. This structure is part of the country's Cold War-era fortifications, built during a period of heightened tensions between East and West. The bunker's designation suggests it was part of a larger network of defensive installations designed to protect against potential aerial or ground threats.
Its location in the Ústí nad Labem Region places it in a historically strategic area, close to the German border and within the former Czechoslovak Socialist Republic's defensive perimeter.
