It is easy to drive past such things without a second glance, mistaking the raised ground for a natural quirk of the landscape, yet what lies here is a rath, a type of enclosed farmstead built during the early medieval period, most commonly between roughly 500 and 1000 AD. Raths were the ordinary domestic spaces of Gaelic Ireland, the homes of farmers and minor landowners, ringed by earthen banks that combined practical enclosure with a visible statement of status.

This particular example is classified as univallate, meaning it has a single enclosing bank rather than the two or three concentric rings found at more elaborate sites. That bank is still impressively well-defined: it rises to a maximum exterior height of 2.6 metres, though from inside the enclosed area the rise is considerably more modest, around 0.9 metres. The bank averages five metres in width, and the circular space it contains measures 25 metres across internally. To the south-west, a fosse, the external ditch dug to provide material for the bank and to reinforce the boundary, survives to a width of three metres and drops roughly 1.1 metres below the level of the surrounding field boundary. The preservation of the fosse, even partially, is noteworthy; such features are often the first things to be lost as land is worked over the centuries.
