caverns
Vast hollow spaces
Caverns is the plural of cavern—a large natural underground chamber, typically formed by water dissolving rock over geological time.
Caverns tend to be larger and more dramatic than caves, often featuring stalactites and stalagmites: We explored the limestone caverns.
Figuratively, any vast hollow space: the dark caverns of the human mind.
