It is irregularly shaped, which is part of what makes it interesting: this is almost certainly a fragment of a tomb surround, a section of the decorative stonework that would once have enclosed a burial monument, likely inside a church or chapel.

What distinguishes the slab is the carved design on its surface, which resembles lierne, a term borrowed from Gothic vaulting. In architecture, lierne refers to the short decorative ribs that connect the main structural ribs of a vaulted ceiling, creating elaborate star or net-like patterns. The same vocabulary of line and geometry could be applied to carved stonework, and that appears to be what a medieval craftsman was doing here. The fragment was recorded as part of the Archaeological Survey of the Dingle Peninsula, published in 1986 by J. Cuppage and colleagues under the imprint Oidhreacht Chorca Duibhne. The fact that it now rests in a private garden rather than in any ecclesiastical or museum setting speaks to the quiet way in which medieval stonework has often survived in Ireland, absorbed into domestic life rather than formally preserved.
