Kergonfalz dolmen

The monument lies in a wood immediately north of the road to Moustoir-Ac. It is about 480 m north of the hamlet that gives it its name, 230 m south-west of the hamlet of Kergal and 200 m east of the hamlet of Saint-Just. About 50 m to the east, on the other side of the road, stands the Kergonfalz covered alley (allée couverte).

The dolmen is of the passage-grave type, but the passage is unusual. The tumulus consists of a layer of dry stone topped by a layer of earth 0.50 m thick. The chamber is rectangular, 2.3 m long, 1.75 m wide and 1.75 m high, with its main axis running north-west/south-east. It is bounded by orthostats and roofed by a single capstone.

The passage is 5.2 m long and 0.80 m wide and runs east-north-east/west-south-west. Its walls are built of alternating orthostats and low dry-stone walls. At 2.4 m from the entrance the height under the roof slabs rises from 0.80 m to 1.50 m. Just before the chamber the passage turns abruptly and ends at the foot of the chamber doorway, which is 0.60 m wide and set in the south corner of the chamber. The whole passage is covered by several roof slabs.
