Doric fountain-house. Two tunnels brought water from the top of the hill to a cistern cut into the rock and closed by a poros isodomic wall in the form of a Ð. Lion-head spouts discharged the water from the closed cistern into a open tank, which was enclosed by six pillars with stone panels between them, and from there to a portico of six Doric columns which formed the facade of the fountain-house (4th c. BC). A sacred law with proscriptions for the protection of the fountain-house was carved on one of the pillars.
