At 1,025 m. a.s.l., a steep path leads up to a plateau in front of the narrow entrance to the cave. On the right side is an antechamber (42 x 19 m.) with a rectangular altar, 1m. high, built of field stones; this area yielded Neolithic potsherds, Early Minoan burials (2800-2200 B.C.), and offerings of the Middle Minoan period (2200-1550 B.C.). In the northern part of the antechamber, at a lower level, a chamber is formed, which included an irregular enclosure with patches of roughly paved floor, forming a sort of a temenos.
