This sanctuary complex is situated on the southern side of Mount Dikte, 1,200 metres above sea level, just above the village of Kato Simi, with fantastic views down to the south coast. A spring emerges from the rocks immediately to the east of the site. The site has been excavated over the last 30 years by A. Lebessi.

Unusually for Crete this sanctuary remained in constant use from the Minoan Protopalatial period up to Roman times. There is some evidence of activity here from MM II, but the first of the remaining structures date from MM III. A Sacred Enclosure was discovered. Together with a paved road and a substantial podium, this constituted a sacrificial area. Cult finds from this area included libation tables, cult vessels and symbols denoting the double axe and horns of consecration.

After the complex was destroyed, most likely by an earthquake, a new building, S, was constructed in the south west corner of the site during the second Neopalatial period. LM IB remains were found in this building but it remained in use right through to LM IIIC.
