Before the tomb was ever raised, people were already gathering here, eating, discarding, leaving behind the compacted remnants of meals and daily life that archaeologists call a midden. What makes this particular spot quietly remarkable is what that midden may also contain: a possible microlith, a tiny worked flint blade of the kind associated with Mesolithic hunter-gatherers, suggesting the headland was a place of human activity long before the monument builders arrived.

The find was recorded by Flanagan in 1984, and the site sits within a wider coastal landscape that clearly attracted successive generations across deep stretches of prehistory. A passage tomb is a megalithic burial monument, typically consisting of a stone-lined corridor leading to a chamber, covered by a cairn or mound, and generally associated in Ireland with Neolithic farming communities from roughly 4000 to 2500 BC. The fact that this one was built directly over earlier midden deposits points to something more layered than simple monument construction. Whether the tomb builders were aware they were raising their structure over older refuse, or whether the accumulated organic material simply made for useful ground, is not something the record tells us. What it does suggest is that the headland carried meaning, or at least sustained use, across a considerable span of time. The site is catalogued under the reference DU008-013001.

The headland lies south of Loughshinney, a small coastal settlement in north County Dublin, between Rush and Skerries. The area is accessible by road, and the low coastal topography means the wider landscape is easy to read on foot. The midden and passage tomb are not visitor attractions in any formal sense, and there is nothing dramatically visible at ground level. What rewards attention here is the layering implied by the archaeology: a shoreline where people camped and foraged, and where, centuries or millennia later, others chose to bury their dead.
