Nine souterrains have been recorded in excavation at the passage tomb complex. They are associated with the early medieval open settlement (ME019-030060-) and are placed largely on the sides and summit of the great mound. This is Souterrain No. 6 and it was structurally attached to the NW corner of medieval house 12 on the side of the mound at its S edge. It consisted of a passage (total L 13.9m; Wth c. 0.75m) with 18 surviving lintels, and only 2 of these were in place. It ran W (L 2.2m), SW (L 3.7m) and then W to a circular chamber (diam. 2.5m; max. surviving H 1.2m). The floor of the passage sloped down steeply (H 2.5m) over its length with 2 steps in its course. It is not conserved.
