The monument belongs to a class known as fulachtaí fia, the most common prehistoric field monument in Ireland. These sites typically consist of a horseshoe-shaped mound of burnt and fire-cracked stone surrounding a trough, where water was heated by dropping in stones from a fire. They date predominantly from the Bronze Age, roughly 1500 to 500 BC, and were used for cooking, and possibly for bathing, textile processing, or other activities requiring large quantities of hot water.

The site at Redbog was recorded in the Sites and Monuments Record in 1987 under the straightforward label of fulacht fiadh, and again in the Record of Monuments and Places in 1996, this time as a fulacht fiadh site, a subtle but telling shift in terminology. The change in designation implies that by the mid-1990s the physical monument had already been levelled, most likely by repeated ploughing. What remains is a burnt spread, the scattered, discoloured residue of the stone and ash that once formed the mound, which shows up as a distinct patch in aerial and satellite photography of the tillage field. An image captured on 13 April 2020 confirms the spread is still legible from above, even if it has effectively ceased to exist as a standing monument on the ground.
