The enclosure is only twenty metres across, defined by a low earthen bank that has been worn down over centuries to little more than a barely perceptible ridge. A modern drain has destroyed the southern section entirely, and the eastern side has collapsed to a simple scarp. There is no detectable outer fosse, which would typically be a defining ditch surrounding an earthen bank, and no clear entrance feature survives. What was once a complete circle is now a fragmentary arc, the kind of site that rewards patience and a willingness to read subtle changes in ground level.

Enclosures of this type are broadly understood as ringfort-like features, a category of monument that proliferated across Ireland during the early medieval period, though the exact function and date of any individual example is rarely straightforward to establish without excavation. What makes the Longorchard site particularly curious is a detail preserved on the first edition Ordnance Survey six-inch map, produced in the nineteenth century: at that point the enclosure was shown not as a bare earthwork but as an irregular grove of trees, apparently associated with a plantation of that era. The trees have since gone, but their former presence suggests the site was at least visible and legible enough in the 1800s to attract deliberate planting, perhaps as a landscape feature or simply because the bank offered a convenient boundary for a small copse.
