It cannot be seen at ground level, and the most prominent feature now marking its approximate location is an ESB electricity pole planted squarely within what was once its interior. That an ancient monument should end up hosting utility infrastructure is not especially unusual in rural Ireland, but it makes for a quietly telling image: a low, flat-topped ridge that once defined a bounded space, now carrying overhead cables across the Clare countryside.

The enclosure first appears clearly on the 1840 edition of the Ordnance Survey six-inch map, where it is shown as a circular form already divided by a field boundary running north-west to south-east. By the time the twenty-five-inch OS map was produced, the record shows an oval area roughly thirty metres east to west and twenty-seven metres north to south, defined by a single enclosing element. Enclosures of this kind are generally understood as early medieval or prehistoric enclosed settlements, related in character to the ringfort, a type of circular earthwork farmstead common across Ireland during the early medieval period. A ringfort does in fact survive roughly 380 metres to the south, suggesting that this part of Derrymore once held more than one such enclosed site. The Derrymore enclosure overlooks a turlough to the north-north-east; turloughs are seasonal limestone lakes, characteristic of the karst landscape of counties Clare and Galway, which flood in winter and dry out in summer, and they were often significant landmarks in early settlement patterns.

There is little to see at the site today, which is perhaps itself worth noting. The ridge is there, the pasture is improved and grazed, and the ESB infrastructure marks the approximate spot. For anyone interested in how thoroughly a monument can be absorbed into an ordinary agricultural landscape while still remaining on the record, Derrymore offers an unusually clear example.
