The oldest Cathedral foundation in Britain, St Deiniol’s Cathedral was founded around 525 AD on the site of a Celtic clas and dedicated to St Deiniol in about 546.The present structure dates back to the early twelfth century when it had an eastern apse and probably an aiseless nave.
It has been considerably altered and rebuilt over a long period and was reconstructed by Bishop Skevington (1509-33) who built the existing nave and western bell tower.
Bishop Skevington’s made arrangements for his heart to be buried near the image of St Deiniol, presumably near the high altar. It is one of the last recorded heart burials in Britain.
