This is a rath, the Irish term for a ringfort, a type of enclosed farmstead typically built during the early medieval period, between roughly the fifth and twelfth centuries. Tens of thousands of them once dotted the Irish countryside; many have been ploughed flat or built over, which makes a reasonably intact example all the more worth pausing over.

This particular rath measures 36 metres in diameter and is defined by two concentric earthen banks with a fosse, or ditch, running between them. The inner bank is the more substantial of the two, standing to an internal height of 2.4 metres and a width of over seven metres in places, though a section of it has been levelled, with the displaced material apparently used to fill part of the fosse to the south-west. The outer bank is lower, around 1.5 metres on its inner face, and survives all the way around except for a wide gap along the north-north-west arc. Trees have established themselves along both banks, which is common in features of this kind and tends to help preserve the earthworks by discouraging cultivation directly over them. The interior of the enclosure slopes downward toward the south-east, and modern field boundaries radiate outward from the north-north-west and north arcs of the outer bank, suggesting that whoever laid out the surrounding farmland did so with the old structure already in place, working around it rather than through it. That small detail, the way later land division bends to accommodate something far older, says something quietly telling about how these features have persisted in the landscape not through formal protection alone, but through the practical habits of generations of farmers who simply found it easier to leave them standing.
