To most eyes it would read as nothing more than a slight irregularity in the field, but within living memory it was something more conspicuous: a high mound, possibly horseshoe-shaped, that was levelled around 1975. What remains beneath the turf is the signature of a fulacht fia, the most common type of prehistoric monument found in Ireland.

Fulachtaí fia (the plural form) are the remnants of ancient cooking or industrial sites, typically Bronze Age in date. The characteristic mound is composed of fire-cracked stone, the accumulated debris of a process in which stones were heated in a fire and then dropped into a water-filled trough to bring the water to a boil. Over repeated use, the shattered, heat-fractured stones were raked out and piled to the side, eventually forming the distinctive horseshoe or kidney shape that archaeologists recognise across the Irish landscape. The levelling of the Cloghboola mound around 1975 was not unusual; many such monuments were removed or disturbed during agricultural improvement works in the twentieth century, often before their significance was widely appreciated at a local level. What makes this particular spot quietly notable is that a second fulacht fia lies only about 40 metres to the north-west, suggesting the area saw repeated or sustained use during prehistory, perhaps because of reliable access to water, which these sites always required.
