underground chambers
Caves beneath earth
Underground chambers are enclosed spaces beneath the earth's surface, whether natural or constructed.
Caves form naturally; crypts, catacombs, and bunkers are built.
The phrase evokes hidden or secret spaces: The explorers discovered underground chambers filled with ancient artifacts.
A single such space is an underground chamber.
