The adyton (Greek: Άδυτον) or adytum (Latin) was a restricted area within the cella of a Greek or Roman temple. Its name meant "inaccessible" or "do not enter". The adyton was frequently a small area at the farthest end of the cella from the entrance: at Delphi it measured just nine by twelve feet. 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.
