What makes Ráithín Uí Bhuaigh stranger still is how legible those layers remain, once you know what you are looking at. The name itself carries the archaeology: ráithín means little fort, a diminutive of ráth, the earthen ringfort enclosures that dot the Irish countryside, and the curving earthen bank that still runs in a rough NW-SE arc through the interior of the graveyard is most likely the surviving remnant of exactly such a structure. The second part of the name, Uí Bhuaigh, appears to be a personal name, suggesting a long-vanished individual or family association with the site.

By 1870, the place had caught the attention of Dayrolles Blakeney de Moleyns, the 4th Lord Ventry, who carried out extensive alterations to what had been a roughly circular early burial ground about 50 metres in diameter, enclosed within an earthen ditch. Lord Ventry planted the sycamores that still stand on three sides, squared off the enclosure, laid a new roadway, built an L-shaped pathway, and added a mausoleum for his own family, recorded on the second-edition Ordnance Survey map of 1896 simply as "Vault". The result is a graveyard of three distinct zones: the older raised inner platform, where a curving earthen bank shelters the densest concentration of early burials marked by cross-slabs, notched headstones, and unhewn stones; an intermediate platform area; and the outer perimeter added in the Victorian enlargement, where more recent interments cluster around the Ventry mausoleum. A survey in 2010 by Laurence Dunne identified at least thirty archaeological artefacts across the site, including fifteen previously unrecorded cross-slabs, several of which date to the 7th and 8th centuries AD. Among the more unusual finds was a single holed-stone, a small perforated slab measuring 0.35m by 0.30m, set within the upper southern limits of the earlier enclosure. Holed or perforated stones are associated with early ecclesiastical sites across the Dingle Peninsula, appearing also at Reask, Kilfountain, and Kilmalkedar, but their precise function remains poorly understood.

The graveyard sits at roughly 50 metres above sea level on elevated ground sloping northward, with Dingle Harbour visible 0.8 kilometres below. It is still occasionally used for burials. The entrance is through modern galvanised gates between rendered piers, and a gravelled path now circuits the interior, though some of the concrete slabs laid during recent works to cover open graves have slipped or partially subsided. The crescent of steep earthen bank curving through the inner ground is the detail worth pausing over; it is, in all likelihood, one of the oldest things here, predating the cross-slabs, the Victorian trees, and the lord's mausoleum by a considerable margin.
