What survives at Leekfield, in Co. Sligo, is a semi-circular arc of slightly raised ground sitting on a gentle rise in ordinary pasture, the southern portion of the enclosure having been removed at some point since the early twentieth century. It is a common enough fate for these sites, yet it gives this one a quietly instructive quality: what remains makes the original form legible precisely because so much is gone.

A ringfort, or rath, is a circular earthwork enclosure, typically dating from the early medieval period in Ireland, and generally understood to have served as a defended farmstead. At Leekfield, the surviving northern half measures roughly 19 metres east to west and 10 metres north to south, defined by a low scarp just 0.6 metres high. There is no fosse, the external ditch that would ordinarily run around the outside of such an enclosure, visible at ground level, and the original entrance can no longer be identified. The 1913 edition of the Ordnance Survey six-inch map records the site as it once was, a roughly circular enclosure complete, which makes the comparison between that depiction and the current remains a straightforward measure of how much agricultural activity can quietly erase in the course of a century.
