Grave 1, 2, 6, 9, 13 and 16 were cist graves built of stone on three sides and a sideways entrance on the fourth side. They were built in the Final Neolithic/Early Minoan I and can be compared to the Cycladic cist graves (type Doumas E) or to mainland-Greece graves form Hagios Kosmas, Marathon/Tsepi and Elis, and to the Final Neolithic graves of Keos-Kephala.
