Most early enclosures in Ireland are roughly circular; this one is shaped like a figure of eight, a double loop measuring approximately 75 metres north to south and 50 metres east to west, its paired ditches still holding waterlogged deposits that have kept organic material intact for centuries.

The site came to light through a geophysical survey and subsequent test-excavation carried out in 2014, licensed under numbers 14R001 and 14E007 respectively, ahead of a planned residential development. What the excavation found in the base of those ditches, which run some 2 metres wide and 1.2 metres deep, was unusually well-preserved: mollusc shells and animal bone surviving in the waterlogged basal fills, the kind of organic evidence that normally rots away entirely in Irish soils. A possible entrance was identified to the northwest. Within the southern element of the enclosure, archaeologists recorded a cluster of internal features including pits, ditches, and what may be a kiln, a structure used for drying grain or firing pottery, though its precise function here remains uncertain. The site does not stand alone either. In the same field to the east lies a ring ditch, a type of monument often associated with prehistoric funerary activity, and to the northeast sits a separate enclosure, suggesting this corner of north Dublin was a place of sustained and layered use.

The enclosure is not publicly accessible as a managed heritage site, and the residential development that prompted the original investigation may have altered the immediate landscape since the excavation report was compiled by Christine Baker and uploaded in February 2015. The record exists primarily in the archaeological licensing system and in Walsh's 2014 excavation report. For anyone researching early settlement patterns along the Dublin coastline, the site is worth knowing about as a document of what lies beneath ordinary-looking ground, even if nothing of it is visible from the surface today.
