The Manning townland ringfort sits atop a natural knoll in pasture ground, and while that detail alone would make it a reasonably well-preserved example of an early medieval enclosure, the more telling fact is that it belongs to a cluster of five ringforts concentrated along the western side of the townland. That kind of grouping suggests not isolated settlement but something more like a community, or at least a landscape in which neighbouring farming families were staking out adjoining territories during the first millennium AD.

A ringfort, sometimes called a rath when its banks are earthen, was the standard enclosed farmstead of early medieval Ireland, typically encircling a family's house, outbuildings, and livestock. This one is roughly circular, measuring about thirty metres east to west and twenty-eight north to south. Its defences are layered: an earthen bank runs from the north-west around to the north-east, while a scarp, essentially a steep-sided drop rather than a built-up bank, handles the rest of the circuit, with a slight internal lip and an intervening fosse, or ditch, adding further definition. An outer stone bank, standing around 0.6 metres high, encircles the whole. There is a break in the banks to the east, almost certainly the original entrance. Perhaps most intriguing is a possible souterrain in the western quadrant of the interior. A souterrain is an underground passage or chamber, usually stone-lined, believed to have served as a place of refuge or cool storage, and their presence within ringforts is reasonably common across Munster, though each one carries its own local uncertainty about what exactly lies beneath.
