That understatement is part of what makes it worth attention. The ring barrow measures roughly 22.9 metres across, and its central mound, only about four metres in diameter and barely twenty centimetres high, would be easy to walk past without registering as anything more than a slight unevenness in the ground.

Ring barrows are prehistoric funerary monuments, typically consisting of a low central mound enclosed by a circular bank and one or more ditches, known as fosses. They belong to a tradition of burial and commemoration that spans the Bronze Age in Ireland, though individual examples can be difficult to date without excavation. At Ironpool, the remains of a fosse survive between the raised central area and the encircling bank, and traces of an external fosse can still be made out running from the north-west, around through the north, and continuing to the south-east. That partial arc suggests the monument was once more fully defined than it appears today, the missing sections perhaps levelled over centuries of agricultural use. The site is described as being in fair condition, which in the language of field archaeology means recognisable but worn.
