The parish church of St Peter ad Vincula (meaning Saint Peter in Chains) in the village of Pennal in Gwynedd, mid Wales, is notable as the site of the last senate meeting held by the renegade Welsh prince, Owain Glyndŵr. It was founded in the 6th century. It is thought that the church was so named by Glyndŵr in competition with the chapel of St Peter ad Vincula in the Tower of London, one of the chapels royal of his rival, King Henry IV of England.
