At Lisnagoneeny in County Kerry, a ringfort once occupied the landscape east of a neighbouring enclosure, its circular earthen bank marking out a farmstead or defended homestead of the early medieval period. Today, nothing remains above ground. The site has been completely levelled, leaving a blank in the field where the enclosure once stood.

Ringforts, known in Irish as raths, were typically circular areas enclosed by one or more earthen banks and ditches, used as farmsteads and sometimes as places of refuge during the early medieval period, roughly 500 to 1000 AD. They are among the most common surviving monument types in Ireland, numbering in the tens of thousands, which makes the loss of any individual example all the more quietly significant. The Lisnagoneeny site was recorded on the Ordnance Survey maps of 1841 to 1842 as a clearly defined circular enclosure. By the time the 1915 to 1916 edition was produced, the outline was already less distinct, suggesting that the earthworks had begun to erode or were being disturbed. At some point after that, the site was lost entirely to levelling, most likely as agricultural land was brought into more intensive use.

What remains is cartographic: the ghost of a circle on two successive maps, separated by roughly seventy years, recording a slow disappearance. C. Toal's North Kerry Archaeological Survey, published in 1995, documented the site among hundreds of others across the region, capturing a record of what had already gone. The placename Lisnagoneeny itself carries a trace of what stood here, since "lios" in Irish refers precisely to this kind of enclosed fort or homestead, preserving in language what the ground no longer shows.
