Set into the nave floor of St Audoen's parish church on High Street, it measures roughly 1.9 metres in length and 0.9 metres across, dimensions that suggest it once marked the resting place of someone of considerable standing. Carved into its surface in low relief, meaning cut shallowly so that the design sits just barely proud of the stone, are a heraldic shield and a Roman-letter inscription. Both have been worn by centuries of foot traffic to the point where reading them requires patience, good light, and a certain willingness to crouch.

St Audoen's is the only medieval parish church in Dublin that remains in use, and its fabric contains layers of the city's ecclesiastical and civic history stretching back to at least the twelfth century. Memorial stones of this kind, set flush with the nave floor so that the congregation would walk over them during services, were a common practice in medieval and early modern churches across Ireland and Britain. The heraldic shield carved on this example would originally have identified the family of the deceased, though the wear on the stone, recorded by archaeologist Geraldine Stout when the entry was compiled in August 2012, has made the device difficult to read clearly. The Roman inscription, likely a dedicatory or funerary formula, is similarly eroded.

The church sits just inside the old city walls near Cook Street, and access to the medieval section is managed separately from the Church of Ireland portion that remains an active place of worship. The interior lighting is modest, which makes examining the floor slab a slightly tricky exercise; a small torch or the light from a phone screen can pick out the shallow relief far more effectively than the ambient light alone. The stone is in the nave, so it is visible from the main pedestrian route through the building, though visitors who are not specifically looking down at the floor tend to miss it entirely. If worn stonework and the quiet puzzle of a half-legible inscription appeal, this is the kind of detail that rewards a slow look.
