This stone was found built into the northern wall of the church during the 1800s. One face bears a six-armed or hexafoil cross set within a circular frame, all drawn with the aid of a pair of compasses. Below the cross are two other simple crosses. A heavily abbreviated inscription using Irish-Saxon letters is set in the frame. Allowing for the abbreviations and some grammatical errors, it appears to translate, '(In the name of Jesus) Christ, Irneit, holy priest, God's bishop in the Island and abbot'. Either side of the two lower crosses are further inscriptions which read, 'In the name of Jesus Christ' and 'The image of the cross of Christ'.
