The townland of Ard Na Caithne, on the Dingle Peninsula in County Kerry, contains a site known as Clochán Dhonncha, and that name is effectively all that survives. A clochán is a dry-stone beehive hut, the kind built without mortar, with corbelled walls that curve inward and upward to form a domed roof. These structures are associated with early Christian monasticism in particular, and dozens of them survive across the Dingle Peninsula in varying states of preservation. Here, the hut itself is gone, but the name preserved in the local Irish placename points firmly to its former existence.

The scholar O'Sullivan, writing in 1937, identified the placename as evidence of a former clochán on the site, a method of recovery that depends on the remarkable tenacity of Irish-language townland and field names. In areas where Irish remained the everyday spoken language into the modern period, these names often encode features of the landscape that have long since vanished physically. Clochán Dhonncha translates roughly as the clochán of Donncha, suggesting the structure was associated with a specific individual, though nothing further is known about who that person was or when the building stood. The site was catalogued in Julia Cuppage's 1986 archaeological survey of the Corca Dhuibhne region, a thorough inventory of the Dingle Peninsula's extraordinary concentration of early medieval and prehistoric remains.
