It exists now only as a record in an archive, its shape preserved not in stone or earthwork but in a faint differential colouring of crops that appeared, briefly, in a Cambridge aerial photograph.

The enclosure was one of three identified from a single aerial image held in the Cambridge University Collection of Aerial Photography, reference CUCAP BDR 29. Cropmarks form when buried features, whether ditches, walls, or filled pits, affect the growth of crops above them; a buried ditch retains more moisture and produces lusher, taller vegetation, while a buried wall does the opposite. Read from the air under the right light and the right season, these subtle differences in growth reveal outlines that have been invisible at ground level for centuries. The Cloghran enclosure was sub-circular in plan, measuring roughly 30 metres east to west and 42 metres north to south. More intriguing still, a tadpole-shaped cropmark sitting eccentrically within the enclosure boundary has been interpreted as the possible remains of a levelled souterrain, an underground stone-lined passage typically associated with early medieval settlement, used for storage or as a place of refuge. The site was compiled for the record by Geraldine Stout and updated by Christine Baker, with an upload date of 22 January 2015.

There is nothing to see at Cloghran today. The site carries the monument reference DU014-014003- in the archaeological record, but the enclosure itself has been built over entirely by the business park. No earthwork survives, no marker acknowledges the buried archaeology, and the ground gives no visible clue to what lies beneath it. The value of the site is archival rather than experiential: it stands as evidence of how much of Dublin's early landscape has been identified only through aerial survey, and then lost before it could be physically investigated.
