Two concentric earthen banks, still roughly circular, describe a space roughly 24 metres north to south and 22 metres east to west. Between them sits a fosse, a shallow ditch that once reinforced the enclosure, and a second fosse runs along the outside. It is the kind of arrangement that becomes visible only once you know to look for it, when the slant of afternoon light catches the low ridges and the ground begins to make a different kind of sense.

This is a rath, the Irish term for a ringfort, the most common monument type surviving in the Irish landscape. Ringforts were typically built during the early medieval period, broadly between the fifth and twelfth centuries, and served as enclosed farmsteads for a single family or small community. The earthen banks, sometimes topped with a timber palisade, defined the household boundary and offered protection for livestock against wolves and raiders. The Camas example is a bivallate rath, meaning it has two banks rather than one, a feature sometimes associated with higher-status occupants, though not exclusively. The inner bank here stands up to 0.7 metres on its outer face and the outer bank reaches 0.45 metres on its inner face, with the best-preserved sections running from the south-east around to the north-west. One detail worth noting is that the external bank has been absorbed into a later field boundary on its north-north-east to east-north-east arc, a reminder of how older earthworks were frequently reused rather than cleared away. The site was recorded and compiled by Denis Power.

The interior is level and grassed over, with no surface features visible. Access is across private agricultural land, so it is worth checking locally before approaching. The earthworks are subtle enough that they reward a patient eye, particularly in low winter or early morning light when shadow emphasises the slight rises in the ground. The surrounding pasture is flat, which means there are no natural contours to confuse the reading of the banks, and the roughly circular outline can be traced, at least in part, from the field edge.
