It is horseshoe-shaped, roughly twenty metres north to south and sixteen metres east to west, rising only about twenty centimetres above the surrounding ground. That modest profile is part of what makes it so easy to overlook, yet it represents one of the most common monument types in the Irish landscape: a fulacht fia, the scorched debris of prehistoric cooking activity.

A fulacht fia is essentially the waste heap left behind by a Bronze Age hot-water cooking method. The process involved heating stones in a fire, then dropping them into a water-filled trough to bring it to the boil. Because the stones crack and shatter when repeatedly heated and cooled, they quickly become useless and are discarded nearby. Over centuries of repeated use, these broken, fire-reddened fragments accumulate into the distinctive mound seen today. The horseshoe or kidney shape is characteristic of the type, with the open side, here facing north-east and roughly three metres wide, typically indicating where the trough once sat. Thousands of fulachtaí fia have been identified across Ireland, with Cork among the counties most densely scattered with them, though the majority are as unassuming as this one: low, grass-covered humps that blend into farmland without any obvious drama.
