There are no inscriptions, no named graves. The enclosure measures around 30 metres north to south and 16 metres east to west, defined by an earth and stone bank and a low scarp, and it is the kind of place that reads, from a distance, as simply a tree-covered earthwork. What it actually represents is something older and more particular: a killeen, the Irish term for an unconsecrated burial ground where, by tradition, unbaptised infants were interred outside the rites of the Church. This one, according to local tradition recorded by antiquarian Thomas Westropp in 1904 to 1905, served exactly that purpose.

The 1840 edition of the Ordnance Survey six-inch map names it Killasragh Childrens Burial Ground, and the accompanying Ordnance Survey Name Books for Killonahan Parish describe it plainly as a burying ground for children and adult strangers. That second category is telling: this was also a place for those who fell outside the normal social and ecclesiastical order, people who died without community or without the sacraments. The site sits within a landscape dense with medieval activity. Immediately adjacent are the earthworks of what may be a deserted medieval settlement and a nearby trackway, while a moated site, a type of enclosed farmstead associated with Anglo-Norman colonisation, lies around 193 metres to the south. Excavations carried out roughly 50 metres to the east, during realignment works on the Cork to Limerick N20 road, uncovered numerous features from the medieval period, suggesting the killeen was once embedded in a functioning, if now largely vanished, community.

When archaeologist Celie O'Rahilly visited the site in 1990 during fieldwork connected to the N20 road project, she noted the enclosure was still intact but heavily overgrown, and observed possible traces of a structural wall along the perimeter. That description still holds. The interior is undulating and difficult to read at ground level, the loose rocks within giving no clear indication of how many burials, if any, survive beneath. The site appears on recent Google Earth imagery as a distinct tree-covered mound, which may help in orienting a visit. It lies in working farmland, so access requires care and courtesy, and the overgrowth means there is little to see beyond the earthwork itself, though that earthwork, and the silence it contains, carries considerable weight.
