Measuring roughly 24 metres in diameter, it is the kind of site that rewards patience rather than spectacle: the enclosing bank has been folded so thoroughly into the surrounding field system that the boundary between ancient monument and modern farmland is almost impossible to trace. The entire northern sector is gone, and a trackway running north to south cuts directly through what would once have been the interior.

Circular enclosures of this type are among the most commonly recorded archaeological features in the Irish countryside. They are generally understood as enclosed settlements, most likely dating to the early medieval period, and are sometimes referred to as ringforts, a broad category that covers both earthen examples (known as raths) and stone-built ones (known as cashels). The earthen bank that once defined this example would have served as a boundary marker and modest defensive barrier for whoever farmed or lived within. What makes the Lattoon example quietly telling is precisely its condition: the way the bank has been incorporated into active field boundaries is not unusual, but it offers a clear illustration of how continuously farmed landscapes in the west of Ireland have layered centuries of land use on top of one another, each generation making practical use of whatever earthworks remained.
