Fountain-house. The facade consists of poros Doric half-columns faced with plaster and supporting an entablature. Panels closed the intermediate spaces. Inside it was an open tank from which the water was drawn (mid-4th c. BC). At a later period (3rd c. BC) the tank was replaced by a well and the columns were carved with the names of the damiourgoi (eponymous priests of ancient Kameiros). Behind the fountain-house the remains of a stoa can be see. A revetment wall on three sides retained the earth fill of the upper terrace.
