The Cave Sanctuaries of the Acropolis of Athens are the natural fissures in the rock of the Acropolis hill that were used as sites of worship for deities of the Panhellenic pantheon in antiquity. Traditionally a sharp distinction has been drawn between the state religion practised on the summit of the Acropolis and the cult practice of the shrines on the lower slopes. Recently, however, interest has burgeoned in the individual religious experience or personal piety in Greek society of which these cult sites may be the expression. The proceeding description follows the order of the shrines from the Klepsydra at the northwest face of the Acropolis clockwise via the Peripatos round to the foot of the Nike bastion.
