Court tombs are among the oldest surviving monuments in Ireland, built during the Neolithic period by farming communities who had only recently arrived on the island. The defining feature of this tomb type is an open, unroofed forecourt, usually semicircular, which leads into one or more roofed burial galleries. Archaeologists believe these courts served a ceremonial function, perhaps for rituals connected to the dead, though the precise nature of those rites remains unknown.

The record of this site draws on the foundational fieldwork carried out by Ruaidhrí de Valera and Seán Ó Nualláin, whose survey of the megalithic tombs of County Mayo, published by the Stationery Office in Dublin in 1964, remains a key reference for anyone interested in the prehistoric monuments of the west of Ireland. De Valera and Ó Nualláin systematically documented court tombs, portal tombs, passage tombs, and other megalithic forms across the country over several decades, and their County Mayo volume captures a landscape that was once far more densely settled and ceremonially active than its present quietness might suggest. Mayo has an unusually high concentration of Neolithic monuments, a reflection of how suitable its soils and coastlines once were for early agriculture before blanket bog spread across much of the region.
