Wedge tombs are the most numerous type of megalithic tomb in Ireland, named for the way their burial gallery tapers in both height and width from front to back. They were constructed during the late Neolithic and into the early Bronze Age, broadly between around 2500 and 2000 BC, and were used as communal burial places. Mayo has a notable concentration of them, scattered across bogland and hillside alike, often overlooked in favour of more celebrated sites elsewhere on the island.

Beyond its classification and location, the particulars of this tomb remain largely undocumented in publicly available sources. No excavation reports, no detailed measurements, no account of what, if anything, was found within it appear to have made their way into the accessible record. That absence is itself telling. Many of Ireland's megalithic monuments, particularly those in rural western counties, were never formally excavated or studied in depth, and their individual histories remain fragmentary. What can be said is that the townland name, Ceapaigh Na Creiche, points to a place with its own long linguistic and territorial history, the Irish word ceapaigh suggesting a plot or tillage ground, though the tomb itself predates any such naming by several thousand years.
