The parish church of St Peter ad Vincula (meaning St Peter in Chains) in the village of Pennal, Gwynedd, Wales is notable as the site of the last senate meeting held by the renegade Welsh prince, Owain Glyndŵr.
A memorial garden has been created in the churchyard for the native Welsh princes. It is thought that the church was so named by Glyndŵr in competition with the chapel of that name in the Tower of London, the chapel royal of his rival, King Henry IV of England.
