he megalithic monuments surrounding the Kerlescan group are particularly interesting.
A large mound (98m long, 15m wide, 2m high) adjoins the northern side of the western enclosure. It has been excavated several times (the last occasion was during the war), but always in precarious conditions.
However, it is known that it covers a set of stone "hearths" and "cists" circled by small standing blocks.
