underground bunker
Subterranean protective chamber
An underground bunker is a fortified shelter built below ground level, designed to protect occupants from bombs, nuclear fallout, natural disasters, or other catastrophic events.
Military bunkers house command centers and personnel during wartime, while civilian versions range from Cold War–era fallout shelters to modern survivalist retreats.
The term often evokes images of apocalypse preppers stockpiling supplies.
They converted an old missile silo into an underground bunker.
