Description

Sources for this section

The capstones of the dolmens show traces of partial dressing, and the plan of every dolmen is of the plate-stone type. The largest capstone, 335 cm long, belongs to the Naega dolmen, the one designated as a monument; the others range in length from 130 to 260 cm. The chambers are cist-shaped, and wedge stones were used around the supporting stones and end stones to make them firm. The floors of the chambers are mostly bare ground, but dolmens 1, 4 and 9 had floors laid with slabs or broken stones.
