It was noted in 1949, assigned a record number, and has not been found since. That particular kind of absence, an object documented and then lost to view, sits at the centre of what makes this site worth knowing about.

The location in question is called Clochán na hEaglaise, named for the structure that does survive: a circular corbelled drystone hut, the kind built without mortar, where each course of stone is laid so that it slightly overhangs the one below, eventually closing into a rough dome. The name translates roughly as the church or chapel clochán, and there is a tradition, recorded by the folklorist and writer Pádraig Ó Siochfhradha, known by his pen name An Seabhac, that mass was celebrated here during the Penal era, the period from the late seventeenth century onward when Catholic worship was suppressed under British law and congregations gathered in remote or concealed places. The possible cross-inscribed stone, which would have added a tangible devotional dimension to that history, was first noted by the Corca Dhuibhne Field Club in 1949, but subsequent researchers working from the survey compiled by J. Cuppage in 1986 were unable to locate it. It may be buried, displaced, or simply easy to overlook on a difficult mountain approach.
