Man-made underground passage in Toberawnaun

Situated on broad rise in gently undulating pasture. Access to the Man-made underground passage is via a roughly square hole (dims. 1m N-S; 1.35m E-W) in the field surface. The entrance gives access to a roughly circular chamber (diam. 4m; H 1.6m) lined with un-mortared limestone rubble. The roof is corbelled. A lintelled opening (Wth 0.4m; H 0.4m) at the base of the chamber wall at E gives access to a passage that appears to extend in an easterly direction.
