The one recorded at Grange in north County Dublin offers no such courtesy. What survives, if survival is even the right word, is little more than a stony patch in a ploughed field, the faint skeletal trace of a settlement that was already being described in the past tense when archaeologists came to look at it.

The site appears on the 1837 Ordnance Survey six-inch map simply as "fort," marked as a univallate circular enclosure, meaning a roughly circular area defined by a single earthen bank or wall, with a diameter of around thirty metres. At the centre was a feature that may have been a house site, the kind of domestic arrangement typical of early medieval Ireland, when ringforts served as farmsteads for families of various social standings rather than as military fortifications. By the time fieldwork was carried out, the enclosure had almost certainly been levelled by repeated cultivation, leaving only a concentration of stones near the apex of the low ridge on which it originally sat. That ridge, modest as it is, would have offered slightly better drainage and a wider view across the surrounding arable land than the fields below, both practical considerations for anyone choosing where to build. Feltrim Hill lies directly to the west. The record was compiled by Geraldine Stout and updated by Christine Baker.

The site sits within working tillage fields, and there is no public monument or marker to indicate where the fort once stood. Visiting requires some awareness of farming activity and the condition of the ground; when the field has been recently ploughed, the stony area near the ridge apex becomes the only visible clue. The 1837 OS map remains a useful reference for orienting yourself to what was once there, even if what greets you on the ground is considerably less legible than the cartographer's neat circle.
