Field systems of this kind, where low earthen banks or stone walls divide the ground into plots, can date back to the Bronze Age or earlier, and in parts of the west of Ireland they survive with remarkable clarity, sometimes only becoming legible when viewed from above or in the long shadows of a low winter sun.

Dumha Éige, whose Irish name suggests a burial mound or ridge, sits within a county that has produced some of Ireland's most significant prehistoric landscape archaeology. The Céide Fields on the north Mayo coast, preserved beneath blanket bog, remain the most celebrated example of an ancient field system in Ireland, but they are far from the only evidence of early organised farming in the region. Field systems like the one recorded at Dumha Éige represent the quiet, everyday infrastructure of prehistoric communities, the divisions of land that determined where crops grew and animals grazed, and that occasionally survived because later populations farmed around them or abandoned the ground altogether.
