ДАП № 4 (DAP No. 4) is a military bunker located in Belarus, near the town of Braslaw. The site is part of Belarus's Cold War-era defense infrastructure, built during the Soviet period to serve as a protected command or communications facility. Belarus, as a former Soviet republic, hosted numerous such installations designed to withstand nuclear or conventional attack.
The bunker's exact operational history and current status are not publicly documented, but structures of this type typically feature reinforced concrete construction and were intended for military personnel during periods of heightened alert.
