That sentence, spare as it is, contains almost everything that can be said with certainty about this site right now. A barrow is a burial mound, typically raised over the dead during the Bronze Age or earlier, and they appear across the Irish landscape in various forms, from large passage-tomb complexes to modest earthen rises that can look, to an untrained eye, like nothing more than a slight irregularity in a field. This one, in the quiet west of Mayo, carries a name that translates roughly from Irish as the green bleaching green or green field, a placename suggesting a patch of ground long noticed and used by the people who lived beside it.

Beyond the classification and the coordinates, the documentary record for this particular monument has not yet been made publicly available, which places it in an interesting category: formally recognised, mapped, given a record number, but not yet described. It is a site that archaeology has acknowledged without yet fully speaking about. Whether the mound is intact, disturbed, excavated, or simply visible as a low rise in the turf is not something the available record confirms.
