It was not a grave in any conventional sense. The skull sat in the edge of a spring, capped as though sealed, in a thin deposit of peat above a spread of burnt stone. Whatever the intention, archaeologists who excavated the site in 2002 were fairly confident it was deliberate, and that the location itself, a watery, liminal place where the ground shifts between dry land and bog, was part of the meaning.

The site at Inchagreenoge came to light during excavations led by Kate Taylor as part of Bord Gáis Éireann's Pipeline to the West project, reference 02E0899. The area examined measured 44 metres by 19 metres and contained several distinct phases of activity ranging from prehistoric to post-medieval. Among the most significant features were two fulachta fiadh, a type of prehistoric burnt-stone cooking site typically consisting of a mound of fire-cracked stones surrounding a water-filled trough, here lined with timber planks and stakes. The eastern spread was roughly 9.5 metres in diameter; the western one measured at least 16.8 by 19.2 metres. A rough wooden trackway, supported by three worked stakes and possibly laid on a bed of deliberately placed grass, was also recorded within the peat, along with a post-medieval stone trackway of limestone slabs, 18 metres long, crossing the bog toward the stream. The peat itself preserved a remarkable range of material: worked wooden mallets, pegs, a small scalloped object, an antler handle, flint scrapers, animal bone, hazelnuts, and fragments of what is probably an 18th-century glass onion flask. The skull, found in the spring at the southern edge of the larger fulacht fiadh, fits into a broader European pattern of deliberate human remains deposited in watery contexts, though Irish examples are relatively rare.

The site itself is not accessible as a visitor destination; it was uncovered during pipeline construction and subsequently recorded rather than preserved in situ. What survives is primarily in the form of the excavation archive, finds, and specialist analysis including planned radiocarbon dating of the skull, the trough timbers, and preserved hazelnuts. For anyone interested in following up, the excavation report is registered under licence 02E0899 and would be held with the National Monuments Service. The broader Pipeline to the West project produced a substantial body of similar roadside archaeology across the midlands and west, much of it published or accessible through the Irish Archaeological Archive, and Inchagreenoge sits quietly among those records as one of the more unusual stops along the route.
