The western end of the slab rests flat on the ground, while the eastern end is propped up nearly a metre and a half into the air, giving the whole arrangement a tilted, suspended quality, as though something beneath it shifted long ago and was never corrected. This is not accidental geology; the slab, measuring roughly 4.3 metres long and over a metre wide, rests on a smaller supporting stone, and to its east stand a narrow upright stone and two low boulder-type stones, the whole grouping quietly insisting on human intention.

The structure belongs to a broad category sometimes called megalithic, meaning simply built from large stones, though what precise ritual or funerary purpose it originally served remains unclear. South-west Kerry is dense with prehistoric monuments of this kind, set into ridges and hillsides across the Iveragh Peninsula, and Canfee is no exception. The elevated position overlooking Kenmare Bay would have been meaningful to whatever community raised these stones, whether as a marker, a gathering point, or a monument to the dead. Without excavation records or surviving oral tradition attached to this specific site, its age and original function can only be estimated by comparison with similar structures across the region, most of which date to the Neolithic or Bronze Age, somewhere between three and five thousand years ago.
