It produced no pottery, no tools, no coins, nothing that might anchor it to a period or a people. What it did preserve was charcoal, layered in fills that tell a quiet story of burning, abandonment, and slow silting over an unknown stretch of time.

The pit came to light during archaeological work carried out by Kate Taylor, excavation reference 02E0847, as part of Bord Gáis Éireann's Pipeline to the West project, a large infrastructure scheme that cut across the Irish midlands and generated a considerable body of archaeological investigation along its route. The feature itself was modest: oval in plan, measuring 1.3 metres by 1.1 metres, and only 0.29 metres deep, with steeply concave sides and a flat base. Its lining of red, oxidised, silty clay suggested burning had taken place directly within it, the heat having altered the surrounding soil in place. Three distinct fills were recorded above that lining. The lowest was a black, charcoal-rich deposit, consistent with burning activity; above it came a light brown, silty clay on the western side, which may represent natural material gradually washing in after the feature fell out of use; and the uppermost fill was a dark brown, charcoal-rich silt. That the charcoal in this final layer may or may not relate to the same burning episode as the primary fill remains unresolved. No artefacts were recovered at all, which leaves the pit entirely undated, though charcoal retrieved through sieved samples was noted as potentially suitable for radiocarbon dating, a technique that measures the decay of carbon isotopes in organic material to estimate age.

There is nothing to see at Adamswood today, and the site itself is not publicly accessible in any formal sense. Its interest lies less in visiting than in knowing it exists: a single, anonymous pit, used briefly for burning, then left to fill with silt and centuries. The excavations.ie database, where this record was compiled by Denis Power and uploaded in August 2012, holds the full report for anyone wanting to read further into what little the ground gave up.
