The structure is a leacht cuimhne, an Irish term for a commemorative monument or memorial stone, and this one is an almost square mortared limestone block set on a plinth, roughly two metres on each side and standing to about the same height. Three of its faces, the north, east, and south, once bore inscribed plaques, though time and displacement have reduced the legible record to a single panel.

That surviving inscription, on the east face and now shifted from its original setting, commemorates a member of the Birmingham family and is dated 1685. The Birminghams were a significant Anglo-Norman dynasty in Connacht, and a monument erected in their name in the late seventeenth century places this structure in a period when such families were navigating the turbulent aftermath of the Cromwellian land settlements and the political pressures that followed. Whether the pier was raised as a funerary marker, a boundary statement, or something closer to a dynastic declaration is not recorded; the other two plaques, on the north and south faces, are no longer legible, so whatever they once said is lost. The structure sits on a prominent rise in otherwise level ground, which would have made it visible across the surrounding grassland, a quality that rarely goes unintended in a memorial of this kind.
