Look closely enough and the surface of the mound betrays two faint depressions, their edges still partly defined by fragments of wall-facing. These are the ghosts of clocháns, the dry-stone beehive huts built without mortar that appear throughout this part of Kerry, and which were once used by early Christian monks and by farming communities across many centuries.

In 1899, the scholar R. A. S. Macalister recorded three of these clocháns arranged in a north-south line at this location. By the time the Dingle Peninsula Archaeological Survey was compiled by J. Cuppage in 1986, very little of the original structures remained traceable above ground. What had once been three distinct huts had effectively collapsed and merged into the cairn visible today, the accumulated rubble of drystone walls folding slowly back into the hillside. The site at Fán is a modest example of something found more spectacularly elsewhere on the peninsula, but that modesty is part of what makes it interesting. It represents the ordinary end of the clochán tradition, the kind of small domestic cluster that has simply worn away with time rather than being preserved or celebrated.
