The adyton (Ancient Greek: ἄδῠτον [ádyton], 'innermost sanctuary, shrine', lit. 'not to be entered') or adytum (Latin) was a restricted area within the cella of a Greek or Roman temple. The adyton was frequently a small area at the farthest end of the cella from the entrance: at Delphi it measured just 9 by 12 feet (2.7 by 3.7 m). The adyton often would house the cult image of the deity. In modern usage, the term is sometimes extended to similar spaces in other cultural contexts, as in Egyptian temples or the Western mystery school, Builders of the Adytum.
