It measures roughly four metres across and rises to about a metre in height, the kind of modest earthwork that a walker might step over without registering its age or purpose. It is, in all likelihood, the remains of an early hut site, a simple rounded dwelling whose walls have long since collapsed inward and been reclaimed by turf.

The Dingle Peninsula is unusually dense with early settlement remains. The area around Mount Eagle in particular, which overlooks the Atlantic and the scattered island shapes of the Blaskets, preserves an extraordinary concentration of field systems, clochán clusters, souterrains, and enclosures. A clochán is a dry-stone corbelled structure, sometimes called a beehive hut, common in early medieval contexts along this coastline. The hut site at Fán was documented as part of the Corca Dhuibhne archaeological survey conducted by J. Cuppage and published in 1986, a systematic effort to catalogue the ancient landscape of this corner of west Kerry before development and erosion could further obscure it.
