A clochán is a dry-stone beehive hut, built without mortar, with walls corbelled inward until they meet at a single point overhead. The technique is ancient, and examples survive across the Corca Dhuibhne peninsula in varying states of completeness, most famously on the Skellig rocks offshore. Seven in one cluster is a notable concentration, suggesting a small monastic or agricultural settlement where people lived, worked, or sought shelter in structures that have outlasted almost everything built around them.

The record of this group derives from the Corca Dhuibhne Archaeological Survey published in 1986, a systematic effort to document the extraordinary density of early remains across the Dingle Peninsula. That survey, compiled by J. Cuppage and published under the imprint of Oidhreacht Chorca Dhuibhne, catalogued hundreds of sites across the area, and this cluster at Fán appears as entry number 1453. The first edition Ordnance Survey maps, produced in Ireland during the 1830s and 1840s, were meticulous in recording field monuments that were already considered ancient at the time, making them an invaluable baseline for understanding what existed before agricultural improvement and development began to thin the archaeological record.
