Less celebrated, but no less ancient, is the fulacht fia recorded in the same townland, a monument type so common across the Irish landscape that it is easy to overlook, yet still quietly extraordinary in what it represents.

A fulacht fia is essentially a prehistoric cooking site, typically consisting of a horseshoe-shaped mound of fire-cracked stone beside a trough, usually timber-lined, that was filled with water. Stones were heated in a nearby fire and dropped into the trough to bring the water to a boil, a method capable of cooking large quantities of meat. Thousands of these sites survive across Ireland, the vast majority dating to the Bronze Age, roughly 2000 to 500 BC. They tend to appear in low-lying, wet ground, which made it easier to fill and maintain the trough, and Gleninsheen, tucked into the limestone terrain of the Burren, would have offered a very different environment in prehistory than the stark, rocky landscape visitors see today. The presence of a fulacht fia here, alongside the famous collar and other Bronze Age material from the valley, suggests the area saw sustained human activity across that period, ordinary domestic or communal life unfolding in a place we now associate almost entirely with a single, spectacular object.
