A fulacht fia is a prehistoric cooking place, typically consisting of a horseshoe-shaped mound of burnt stone and charcoal that accumulated beside a water source as heated rocks were repeatedly plunged into a trough to boil water. What survives at Ardaprior is now largely a denuded spread rather than an intact mound, measuring roughly 24 metres east-west and nearly 13 metres north-south, sitting on the south-east bank of a small stream.

For most of its existence the site was probably just another unremarkable lump in the pasture, the kind that farmers learn to work around. In August 1994, however, local information confirms that the mound was levelled, reducing most of it to the flattened spread visible today. A small remnant section along the stream edge still holds some height, reaching about 0.6 metres, and extends roughly 8 metres in length. What gives the location a particular quiet interest is that it does not stand alone. Approximately 170 metres to the north, on the opposite bank of the same stream, a second fulacht fia survives. The pairing is not unusual in itself, as these sites often cluster near reliable water sources, but taken together the two monuments suggest repeated or sustained activity along this particular stretch of water at some point in prehistory, most likely during the Bronze Age when the vast majority of Irish fulachta fia are thought to have been in use.
