It is the kind of monument that registers as a presence in the landscape before it registers as anything else, a deliberate accumulation of stone in a place where the mountains come down sharply to the water and the ground offers little obvious reason for ceremony unless ceremony was precisely the point.

Cairns of this type are scattered across the west of Ireland, many of them dating to the Neolithic or Bronze Age periods, roughly between five thousand and three thousand years ago. They were raised for purposes that varied considerably, from covering the remains of the dead to marking territorial edges or significant points in the landscape. An Más sits within a stretch of south Mayo that retains a considerable density of prehistoric monuments, a reflection of how long this coastline has been occupied and how seriously its earlier inhabitants treated the business of marking place. Beyond its classification as a cairn and its location in this townland, the specific history of this particular mound remains undocumented in any publicly available form.
