Wedge tombs are the most numerous megalithic tomb type in Ireland, built roughly between 2500 and 2000 BC during the late Neolithic and early Bronze Age, and Clare has more of them than almost anywhere else. The form is distinctive: a roofed gallery that narrows and lowers towards the rear, typically oriented to the west or south-west, possibly aligned with the setting sun. That basic shape has endured in the landscape for four millennia, which makes each individual example easy to overlook and, in its own way, all the more worth pausing over.

The tomb at Cloghoolia is documented in the landmark 1961 volume by Ruaidhrí de Valera and Seán Ó Nualláin, the first instalment of their systematic survey of Ireland's megalithic tombs, covering County Clare in particular detail. De Valera and Ó Nualláin catalogued dozens of such monuments across the county, establishing the framework through which wedge tombs in Clare are still understood and classified. Their work brought rigour to what had previously been a rather scattered body of knowledge, and the Cloghoolia tomb was among the sites they recorded and described. Beyond its inclusion in that survey, the specific structural details of this particular monument are not extensively documented in surviving notes, which itself says something about how many of these sites exist, spread quietly across Irish townlands, known to local farmers long before they were known to archaeology.
