Not ruined, not overgrown, but actively cleared, leaving the improved pasture south of Carrickgollogan as smooth and unremarkable as any other field in the area. What makes the site quietly extraordinary is that it has not entirely disappeared; it simply requires a different way of looking. From the air, cropmarks reveal the ghost of the enclosure, two levelled banks with external fosses running from the south-south-east to the south-west, the buried geometry of the place still influencing what grows above it.

The site has a complicated cartographic history. The 1843 Ordnance Survey six-inch map recorded it as a large univallate enclosure, meaning a single-banked circular earthwork of the kind built throughout Ireland from the early medieval period onwards, typically enclosing a farmstead or high-status dwelling. By the time the 1937 Ordnance Survey edition was produced, the record showed the northern half of a bivallate enclosure, one with two concentric banks, with an internal diameter of roughly 80 metres and an external diameter of approximately 120 metres. Whether the discrepancy between the two maps reflects an error in the earlier survey, subsequent changes to the site, or differing interpretations by surveyors is not entirely clear. What is clear is that the site was cleared around 1950, after which nothing remained visible at ground level. Archaeological test excavation in 2002, carried out as part of an assessment for a proposed Dún Laoghaire Golf Course, confirmed the buried remains and recovered medieval pottery from the fill of the fosses, placing at least some of the site's activity within the medieval period. The aerial photograph referenced in the archaeological record, catalogued as CUCAP BDP 22, also shows linear cropmarks to the south-east of the enclosure that may indicate an associated field system.

The site sits in working farmland and there is nothing to see on the ground itself. The interest here is largely for those drawn to the idea of landscape archaeology, the knowledge that significant and complex earthworks can be entirely erased within a human lifetime yet remain legible through other means. The surrounding area offers context: the slopes of Carrickgollogan to the north and clear southward views toward the Sugar Loaf Mountain give a sense of the elevated, open position that whoever built the enclosure would have chosen deliberately. Access to the field itself is subject to landowner permission, but the aerial photograph and the 2002 excavation report by Byrne provide the clearest picture of what lies beneath the grass.
