Called Ro 4/Sheegeeragh Td. 2 by Herity in Irish Passage Graves, he identified this as a passage grave, along with two others nearby, one about 100 metres away which we couldn’t visit because of the horses in the field, and the other 700 metres to the south of this (Ro 3/Sheegeeragh Td. 1, Caran Hill). I thought it was a wedge tomb until I checked.
