The monument consists of an inscribed stone, a commemorative monument which has been inscribed with letters and symbols, probably dating to the early-medieval period (c. AD400-AD1066 the period between the breakdown of Roman rule and the Norman Conquest). The stone has been built into the S wall of the farmyard at Llystyn Gwyn. It measures 1.05m by 1.06m by 0.33m thick with a Latin inscription 'ICORI FILIVS / POTENTI / NI' (Icorix, the son of Potentius) in the top right corner and an Ogham inscription 'ICORIGAS' (of Icorix) along the upper right side. The Latin inscription is still visible, but the Ogham is barely discernable.

The monument is of national importance for its potential to enhance our knowledge of ritual and funerary practices and the organisation and practice of early-medieval Christianity. It retains significant archaeological potential, an inscribed stone may be part of a larger cluster of monuments and their importance can further enhanced by their group value.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
