This one is remarkable for what does not. On the first edition of the Ordnance Survey map, a circular enclosure near Meennascarty is clearly marked and labelled simply "Fort" on the Fair Plan, the working document surveyors used to record features before final publication. By the time the second edition was produced, roughly half of that circle had already gone, the south-western portion removed sometime before the late nineteenth century. Today, nothing of the earthwork remains visible on the ground at all.

The site in question was a rath, the Irish term for a ringfort, the most common type of early medieval settlement in Ireland. These enclosures, typically formed by one or more earthen banks and ditches, served as farmsteads for farming families roughly between the fifth and twelfth centuries. They number in the tens of thousands across the country, yet a great many have been quietly erased by agriculture, drainage, and development, often without any formal record of their loss beyond the gap between one map edition and the next. At Meennascarty, the fort once sat on level ground approximately fifty metres east of the Meennascarty river, and about half a mile south of Tralee Bay on the Dingle Peninsula. The landscape around it is unremarkable to look at now, which is precisely the point. The 1986 Dingle Peninsula archaeological survey by J. Cuppage documented the site and noted its already-advanced disappearance, preserving at least a paper outline of something the land itself no longer holds.

What the OS maps preserve, then, is a kind of negative archaeology, the shape of a place recorded just in time to confirm its loss. The gap between the first and second edition printings becomes the entire history of the site's destruction.
