No earthworks break the surface, no obvious mound or hollow signals that anything is there. Yet beneath the grass, a sequence of at least four nested enclosures lies quietly in the soil, invisible without the instruments that eventually found them.

The site came to light through a gradiometer survey carried out in 2023 by D. Murphy, a form of geophysical investigation that detects subtle differences in the magnetic properties of buried soil features, such as filled ditches or fosses. What that survey revealed is a complex, layered arrangement. At the centre sits a roughly circular enclosure around 20 metres across, positioned slightly off-centre within a larger subcircular enclosure measuring approximately 45 metres north to south and 40 metres east to west. That second enclosure in turn sits inside a D-shaped area around 80 metres by 65 metres, which is itself contained within a still larger D-shaped arrangement roughly 110 metres east to west and 90 metres north to south. The outermost ditches of the two larger enclosures appear to have merged or grown from one another rather than being wholly independent, suggesting the site developed over time rather than being laid out in a single phase. Complicating matters further, a small oval enclosure, around 20 by 15 metres, is clipped by the northern perimeter of the second enclosure, as though it predates it or was simply in the way. Lighter features within the complex resemble field drains, some of them creating small plots attached to the inner enclosures, while straighter north-south and east-west drains further out are probably the remnants of an unmapped post-medieval field system. The two outermost enclosures are bisected by a service road running to the Drogheda cement factory, a mundane interruption that slices across whatever boundary these ditches once defined.

The purpose of the enclosures is not recorded and no date has been assigned to them. Concentric enclosures of this general character are known elsewhere in Ireland in prehistoric and early medieval contexts, used variously as settlement sites, ceremonial spaces, or places of high-status occupation, but without excavation the function here remains open. What is clear is that this hillside, with its long view over the Boyne, once held something considered worth enclosing, and enclosing again, and perhaps again after that.
