The site was once close to the confluence of the King's River and the River Liffey, a meeting of waters that has since been swallowed by the reservoir created to serve Dublin's water supply. Before the flooding, in 1934, a cist was uncovered there: a short stone-lined box grave measuring just 0.75 metres by 0.42 metres, barely large enough to hold what it contained.

The cist was excavated by Liam Gógan and found to contain two inverted ceramic vessels. One was an encrusted urn, a type of decorated Bronze Age pottery typically associated with cremation burials, and the other was a vase food vessel, a smaller pot thought to have been placed with the dead as an offering or accompaniment. Both were placed upside down, a deliberate arrangement seen in other Irish Bronze Age burials of the period. Decades later, analysis of the cremated remains by Laureen Buckley brought a more personal dimension to the find. The bones belonged to a female who was between thirteen and fifteen years old at the time of her death. Among the cremated material, two convex end scrapers and a fragment of broken flint were also identified; small stone tools whose presence alongside the burial may reflect personal possessions or ritual deposit. The site is now inaccessible, permanently beneath the water, but the objects and the analysis that followed preserve something of the individual, a young woman interred with care at a river confluence that no longer exists above ground.
