Giants Grave — Aghagashlan

This dual court tomb is sited on a low ridge. The structure is incorporated in an oval mound, aligned E-W, 23m long, 17.5m wide and 1.5m high. At W two facade-stones articulate with the S arm of a court of semicircular outline. The court at the E end of the cairn seems to have been of a more elongated design. Longitudinally-set jambs mark the entries to both galleries. The eastern gallery, represented by two sidestones at the S and a backstone, is 5m long. The western gallery, represented by a single sidestone at the S, was at least 5m long. It is not clear if both galleries shared a common backstone. The lengths of the galleries would suggest each was of two chambers.
