Pabo Post Prydain was a king somewhere in the Hen Ogledd or Old North of sub-Roman Britain.

According to Old Welsh genealogies, which were largely produced to prove a monarch's royal pedigree, Pabo Post Prydain (Pabo Pillar of Britain) inherited his kingdom from his father Arthwys ap Mor, a great grandson of Coel Hen. Historians conjecture that he may have ruled in the Pennines or around Papcastle in Cumberland (now Cumbria) in the 6th century. Pedigrees of descent for two of his sons - Sawyl Penuchel and Dunod Fawr - are known, perhaps suggesting a later division of his kingdom.

Pabo is sometimes identified with Saint Pabo who died and is buried at Llanbabo on Anglesey. If so, he presumably abdicated in order to retire in the west.

Ystradwel’s grandson, Pabo Post Pydein, Pabo ‘Pillar of Britain’, the son, according to the earliest genealogical sources, of Ceneu ap Coel Hen joined in the struggle to secure the vulnerable coastal lands. He was the cousin of Einion Yrth and it appears likely that prompted by the premature death of his kinsman he came to the assistance of Einion Yrth’s sons.

Pabo’s base in north Wales was strategically situated on a raised ledge of land on a hillside overlooking the broad sweep of the Conwy estuary. The site has a clear, uninterrupted view of the eastern approaches to the Menai Strait, but is itself virtually invisible to anyone on the valley bottom.

The enclosure has retained the name Pabo and the narrow track winding down to the estuary and what was once a Roman port is Lôn Pabo, Pabo’s Lane.

‘There was an ancient Tradition in the parish of LanBabo in Anglesey that Pabo with his Son and Daughter were buried in the Churchyard opposite to certain faces that were carv’d in the Wall, and to be seen to this Day. In King Charles ye 2nd’s Time or there about (as I was Inform’d) the Sexton happened to dig a Grave agst one of these carved Faces, at about six or seven feet deep, found a flat Grave stone, one corner of wch he pick’d, and demolished a few letters before he knew what it was. The stone was then remov’d into the Quire, where it hath remained ever since….’

                                   Letter from Lewis Morris to Mr. Carte, written c. 1745

The late fourteenth century memorial slab erected in honour of the memory of Pabo, Post Pridd, the fifth century founder of the church, is now set upright against the north wall of the Nave. The intricate carving depicts Pabo as a king of the Middle Ages with crown and sceptre, his head resting upon a cushion. He has a neatly trimmed beard and moustache and his hair hangs down in curls to below the ears.

The sandstone slab was defaced and broken probably at the time of the Reformation and the pieces later buried in the graveyard for safekeeping.

Llanbabo is situated in the north of Môn close to Llyn Alaw, four miles from the ‘Copper Mountain’, Mynydd Trysglwyn. It is one of the earliest Christian churches to have been founded on the island and the local traditions is that it was built on or near the site of one of the battles that freed the land from the Irish invaders.

Pabo’s grandson Deiniol ap Dunod Fwr founded the cathedral at Bangor on Menai.

His brother Gwrwst Ledlwm ‘Gwrwst the Ragged’ ap Ceneu is mentioned in Culhwch ac Olwen as having being taken prisoner by Gwyn ap Nudd.

Dunod Fwr ap Pabo was remembered as one of the ‘Three Pillars of Battle’ of Ynys Prydein. The Annales Cambriae record his death as being in 595, but this seems to be unlikely, unless he lived to a great age, as his son Deiniol died in 584. -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------St. Pabo Post Prydein, King of the Pennines (c.474-530) (Welsh: Pabo; Latin: Pabius; English: Pabio) Pabo Post Prydein, is most popularly called the son of King Arthuis, though earlier sources suggest that he was this man's brother. His epithet means the Pillar of Britain, said to derive from his keeping Pictish invaders at bay. Though his Kingdom covered the Pennines of central Britain, in later life, Pabo turned to Christianity, abdicated the throne in favour of his sons, Dunaut Bwr and Sawyl Penuchel, and retired to Gwynedd where he founded the church of Llanabo on Ynys Mon (Anglesey). He died there on 9th November 530 and a beautiful medieval stone slab carved with his image can still be seen covering his grave.
