consists of "8 superimposed stone rings - average thickness 1.40m", each developed at different elevation levels, with the highest surviving section at 1.7 meters tall.

A 15-meter diameter circular building dubbed "Zone A" stood in the center surrounded by the rings, with its nine-meter wide interior divided into 4 quadrants.

Surrounding Zone A was a second circular building 6.9 meters wide, whose radial walls "intersect vertically the rings of the lower levels forming smaller spaces".

Excavators estimated that the structure was mainly used between 2000 and 1700 BCE, being constructed roughly around the beginning of the Protopalatial period (MM IB).

The construction did have structural similarities to vaulted tombs in southern Crete from the pre-Hellenic Prepalatial and Protopalatial periods, and also to ancient mounds found in the main body of Greece.
