B/316 is a military bunker located in the Czech Republic, near the town of Hradec Králové. The structure is part of the country's Cold War-era fortifications, built during a period of heightened tensions between NATO and Warsaw Pact nations. Czechia, as a former member of the Warsaw Pact, maintained an extensive network of defensive installations throughout the latter half of the 20th century.
This bunker represents the strategic military planning that characterized the region during the Cold War period.
