A rath, as these earthwork enclosures are commonly called, was typically formed by a circular bank and ditch enclosing a domestic or agricultural space, and for much of early medieval Ireland they were among the most familiar features of the rural landscape. This one, measuring around 40 metres in diameter, has been completely levelled, leaving no visible surface trace whatsoever. The field is worked, the ground is flat, and only the documentary record confirms that anything was ever there.

The fort's existence is known primarily from the Ordnance Survey's 6-inch map of 1842, which recorded it as a circular enclosure sitting alongside a road running roughly northwest to southeast. At that point it was still sufficiently legible to be mapped and noted. At some stage afterwards, agricultural activity erased whatever earthworks remained. The area around Sarsfieldscourt holds at least one other prehistoric marker: a standing stone lies approximately 120 metres to the west, a solitary upright stone whose original purpose, whether boundary marker, monument, or something else entirely, is now uncertain. The two features may or may not have been related in any meaningful way, but their proximity is suggestive of a landscape that was once more legibly occupied than it now appears.

For anyone inclined to visit, the honest reality is that there is nothing to see at the ringfort site itself. The standing stone to the west is the only tangible feature remaining in the immediate area.
