That, in its entirety, is what survives at Courtlough in north County Dublin, and yet the very modesty of the find is what makes it worth pausing over.

The site came to light during topsoil monitoring in 2003, the kind of routine archaeological watching brief that accompanies road and development work across Ireland. What it revealed was a scatter of pits and post-holes along the northern flank of a low glacial ridge, the sort of slight natural elevation that would have offered a dry footing above the surrounding wetland. Follow-up excavations the same year exposed the central feature: a shallow depression packed with heat-shattered stones, itself cut into by a later oblong pit. The single piece of flint debitage, a waste flake produced when knapping flint into tools, and the small fragment of burnt bone are the only material traces recovered. The site is recorded in the work of Murray (c. 2006) and was compiled for the Irish record by Geraldine Stout. The precise date of the feature is not established, but burnt-stone sites of this kind are broadly associated with prehistoric activity, and the combination of heat-cracked stone, a ridge edge, and adjacent wetland fits a pattern seen at fulachta fiadh across Ireland. A fulacht fiadh is a type of ancient cooking or industrial site, typically identified by a mound of fire-shattered stones beside a water source, though the term is not applied explicitly to Courtlough in the available record.

Courtlough is a townland in the Balbriggan area of north County Dublin. The site itself is not marked or interpreted for visitors and there is no formal access point. The low glacial ridge and the wetland setting described in the excavation notes are the landscape features most likely to orient anyone searching for the general area. For those with an interest in field archaeology, the significance here lies less in what was found than in what the monitoring process itself demonstrates: that even unremarkable-looking agricultural ground in the Dublin hinterland can preserve traces, however faint, of lives lived close to the water's edge.
