The site is documented in Ruaidhrí de Valera and Seán Ó Nualláin's foundational work, the Survey of the Megalithic Tombs of Ireland, Volume I, covering County Clare, published by the Stationery Office in Dublin in 1961. That survey remains the essential reference point for Clare's prehistoric burial monuments, cataloguing the county's court tombs, portal tombs, wedge tombs, and related structures with methodical precision. Megalithic tombs of this kind were constructed during the Neolithic period, roughly four to six thousand years ago, and were used as collective burial places, their large upright stones and capstones assembled without mortar, relying entirely on weight and placement. The place name Poulnabrucky offers its own quiet clue to the landscape; "poul" derives from the Irish "poll", meaning a hole or pit, a word commonly attached to places with noticeable hollows or caves in the limestone terrain of Clare.
