Wedge tombs are the most numerous type of megalithic monument in Ireland, built during the late Neolithic and into the early Bronze Age, roughly four to five thousand years ago. Their name comes from their shape: a roofed gallery that narrows and lowers from front to back, typically oriented to the west or south-west, possibly in alignment with the setting sun. The Knockadoon example belongs to this widespread but often understated tradition of collective burial and monument-building.

The principal scholarly record for this tomb comes from the fieldwork of Ruaidhrí de Valera and Seán Ó Nualláin, published in 1964 as part of their systematic Survey of the Megalithic Tombs of Ireland, the second volume of which covered County Mayo. De Valera and Ó Nualláin spent years documenting megalithic monuments across the country, and their Mayo volume brought together detailed measurements, orientations, and structural observations for sites that might otherwise have remained unrecorded in any systematic way. The Knockadoon tomb is among those catalogued in that effort, which remains a foundational reference for Irish prehistoric archaeology.
