In a narrow valley running north-north-east from Dingle town, there was once a ringfort, a circular earthen enclosure of the kind built in early medieval Ireland as a farmstead and defended homestead. It appeared on the first edition of the Ordnance Survey map, where it was labelled simply as 'Fort' on the Fair Plan, the working document from which the published maps were drawn. At some point between that survey and the present, the enclosure was removed entirely, levelled back into the fields that surround it.

Ringforts, known in Irish as raths, were typically constructed between roughly the sixth and tenth centuries, though many were built earlier or later. They consist of one or more circular banks and ditches enclosing a domestic area, and they are among the most common field monuments in Ireland, numbering in the tens of thousands. That makes their destruction all the more dispiriting; these were never rare features. This particular example, catalogued by J. Cuppage in the 1986 Dingle Peninsula archaeological survey, sat in what would have been a sheltered spot, the valley floor offering some protection from the Atlantic weather that shapes so much of the Corca Dhuibhne landscape. Whether it was ploughed out, built over, or simply worn away by agricultural use over the generations is not recorded.
