The interior of this ringfort, which measures roughly 28 metres across, has been landscaped with trees and fitted with a pump house and watering trough, giving it a doubled life as both early medieval enclosure and working farmyard feature. That layering of uses, centuries apart and entirely unself-conscious, is what makes the place quietly arresting.

A rath, as this type of ringfort is known, was typically a farmstead of the early medieval period in Ireland, defined by one or more earthen banks and an external fosse, which is a drainage or defensive ditch, enclosing a circular area where a family might have lived, kept livestock, and stored food. At Ardskea Beg the bank is degraded, worn down over time, and a later field wall has been built directly over part of it, running from the south-east round to the south. That wall represents exactly the kind of quiet erasure that happened to thousands of such monuments across the country, as later agricultural generations found the existing earthworks convenient boundaries rather than objects of preservation. A possible causeway is still visible on the eastern side, crossing the fosse at what would have been the original entrance point, suggesting something of the original approach to the enclosure has survived in the landscape even as the rest was absorbed into farm use.
