But the one uncovered at Darcystown in County Dublin held something quietly remarkable: a concentrated deposit of decorated Neolithic pottery, carefully placed or discarded there by people who lived in this part of Ireland somewhere around 3,700 BC, making it older than the pyramids at Giza and contemporary with the earliest phases of Newgrange.

The pit was excavated under licence number 03E0067 ahead of a development on the site, the kind of investigative work that routinely precedes construction in areas of archaeological sensitivity in Ireland. Measuring 0.76 metres by 0.65 metres, it is a modest feature by any standard, yet the quantity of decorated pottery recovered from it was significant enough to draw attention. Radiocarbon dating of material from the fill produced a calibrated date range of 3700 to 3630 BC, placing it firmly in the Neolithic period, the era when farming communities first began to establish themselves across Ireland. The pit sits to the northeast of a flat cemetery recorded in the national monuments register, a flat cemetery being a burial ground without visible above-ground markers, which suggests this corner of north County Dublin was a place of some ongoing human significance over a long span of time. The findings were published by Carroll and colleagues in 2008.

There is nothing to see at Darcystown today in the conventional sense. The pit was excavated in advance of development, which means the landscape above it has almost certainly been altered since the investigation took place. For those interested in this kind of material, the published record compiled by Christine Baker and available through the Irish national monument databases offers the clearest picture of what was found. The significance of the site lies less in any surviving physical feature and more in what the pottery represents: evidence of a community active in this part of Dublin over five and a half thousand years ago, leaving behind decorated vessels whose precise purpose, whether ritual, domestic, or something in between, remains open to interpretation.
