The site at Paddinstown is a rath, the more technical name for a ringfort, which was the standard form of rural settlement in early medieval Ireland. Typically consisting of a raised earthen bank enclosing a roughly circular area, these structures served as farmsteads, offering a degree of protection for a family and their livestock. Tens of thousands once existed across the island; many have been ploughed flat or built over, which makes the survival of even a partial example quietly significant.

What remains at Paddinstown is a circular enclosure of approximately 36 metres in diameter, defined by an earthen bank with a gap on the north-east side, most likely the original entrance point. This north-east orientation for entrances is common among ringforts and is thought to relate to prevailing winds, the movement of livestock, or possibly solar alignment, though no single explanation commands universal agreement. The site sits roughly 200 metres to the north-north-west of a second ringfort in the same area, a proximity that hints at the density of early medieval settlement across this part of the Irish midlands, where such enclosures were once a routine feature of the farmed landscape.
