Between 1970 and 1973 three campaigns of excavations have been conducted by a French team headed by Alain Le Brun.
Sometimes several of these are arranged around a common courtyard or stand on small platforms levelled into the hillside.
Only one house has a more substantial wall (1.70 m thick) and the excavator thinks it might have had a function different from the rest of the structures.
It is believed they may have been used to prepare food or to smoke meat, in the manner of the Polynesian pit ovens or the Irish fulachtaí fia.
One burial was discovered in a shallow trapezoidal pit measuring 0.75x0.45 m. The body lay on the back, with flexed legs, the head to the northeast, the face turned to the southeast.
