It measures roughly nine metres north to south and just over eight metres east to west, rising only about half a metre from the ground, with an opening three metres wide facing north-west. To a passing eye it might look like nothing more than a slight rise in a field. In fact it is the remains of a fulacht fia, a type of Bronze Age cooking or processing site found in considerable numbers across Ireland, typically near water sources.

Fulachta fiadh, the plural form, are among the most common prehistoric monuments in the Irish countryside. The mounds are composed of burnt and fire-cracked stone, the accumulated debris of a process that involved heating stones in a fire and dropping them into a water-filled trough to bring the water to boiling point. The horseshoe shape is characteristic, with the open end often positioned near the water supply and the curved mound forming from the discarded stone over repeated use. The site at Curraduff is particularly notable because it does not stand alone. It is one of a cluster of four such monuments in the immediate area, suggesting sustained or repeated activity at this location during prehistory. A drain runs along the northern edge of the site, and the proximity to the stream would have made the location well suited to the water management that these sites required.
