Definition & Meaning of "dungeon"

What is a "dungeon"?

A dungeon is an underground room or cell, typically found in castles or fortifications, used for imprisonment or storage. Historically, dungeons served as dark, cold spaces for holding prisoners, often those accused of crimes or enemies of the state. These rooms are usually constructed with thick stone walls and minimal light, creating a secure environment that is difficult to escape from. Dungeons may also be used for other purposes, such as storing weapons, food supplies, or valuables. Over time, dungeons have become associated with tales of mystery and adventure, often depicted in literature and folklore as places of danger and intrigue.
