It has no marker, no interpretive panel, and no surface trace of any kind. The only record of its existence is a single aerial photograph taken in 1970, before the ground above it was built over entirely.

The photograph captured what archaeologists call a cropmark, a phenomenon where buried features affect the growth of plants above them, making ditches or walls faintly visible from the air as differences in colour or height in the vegetation. In this case, the image revealed a roughly circular enclosure with traces of an outer enclosure surrounding it, and a rectangular feature lying to the south-east. Circular enclosures of this general type are found across Ireland in considerable numbers and are associated with early medieval settlement, though the Balcurris example was never excavated before development removed any practical chance of ground investigation. The site sat on relatively level ground, with a stream running along to its west, a setting typical of such enclosures, which were often positioned near water. The record was compiled by archaeologist Geraldine Stout and uploaded to the national sites database in August 2011.

There is, in honest terms, nothing to see at Balcurris today. The coordinates place the original site within an area of suburban north Dublin, in the Ballymun district, where residential streets and retail development have long since replaced any visible archaeology. For anyone interested in how thoroughly the past can be erased by twentieth-century urban expansion, that absence is itself quietly instructive. The 1970 aerial photograph, taken just in time, remains the sole documentation of a site that might otherwise have passed out of the record entirely.
