On a residential patch of ground in Ballysaxhills, County Kildare, the past has been almost entirely absorbed by the ordinary business of domestic life. Cottages and their gardens now occupy the spot where, according to cartographic evidence, something considerably older once stood, and nothing visible on the surface gives any hint that it was ever there.

The sole record of what may have been here comes from Taylor's 1783 Map of County Kildare, which marks a small circular feature in this general area. That circular outline is consistent with a ringfort, the most common type of early medieval enclosed settlement in Ireland, typically formed by one or more earthen banks and ditches enclosing a farmstead or dwelling. Ringforts are found in their thousands across the Irish countryside, yet a great many have been lost to agriculture, development, and time. Whatever stood at Ballysaxhills left no trace on the ground that survives today, and the 1783 map remains the only indication that something was once deliberately enclosed here.
