In a pasture near the townland of Ballinanima in County Limerick, there once stood a raised circular earthwork, a platform or mound defined by a scarp, which is the steep face of an earthen bank, typically marking the edge of a deliberately constructed feature. It was ordinary enough to be recorded, and ordinary enough, it seems, to be quietly erased.

The earthwork appears on the 1840 edition of the Ordnance Survey Ireland six-inch map, depicted as a raised circular-shaped area roughly 250 metres west of the townland boundary with Ballyrow Lower. By the time the 25-inch map edition was published in 1897, the feature had vanished from the record entirely. The implication drawn by researcher Fiona Rooney, who compiled the site record in August 2021, is that the earthwork was levelled sometime in the intervening decades, most likely cleared to improve agricultural land. It would not have been an unusual fate. The nineteenth century saw enormous pressure placed on marginal ground across Ireland, and features that had survived for centuries were removed with relatively little ceremony as pasture was extended and improved.

Today there is nothing to see. Satellite imagery from Digital Globe, taken between 2011 and 2013, shows no surface trace, and later Google Earth orthoimages confirm the same blank picture. The land has absorbed whatever was there. For anyone interested enough to visit, the location is working farmland, and the experience is less one of discovery than of reading an absence, knowing where to look precisely because the maps tell you something is gone. The value here is archival rather than visual: a reminder that the landscape carries erasures as well as survivals, and that the 1840 survey caught something in its last years of existence that no later record bothered to preserve.
