The hill of Craig-y-dorth, 1 milenorth east of the church, was the site of a battle in 1404 between Owain Glyndŵr's army and English forces. According to the Annals of Owain Glyn Dwr, "There the English were killed for the most part and they were pursued up to the gates of the town". The hamlet of Craig-y-dorth is one of the only two communities in Monmouthshire with its own flag, the other being the town of Monmouth.
