6th century. Almost nothing is known about Saint Tudno beyond the Welsh
traditions that refer to him. Llandudno in Carnarvonshire was named for
him
(
Benedictines).
More information from a list member, Noel at Llandudno:
Greetings, Father Emrys, for the feast of Saint Tudno, from Llandudno in
North Wales. The parish of Llandudno is an island in the ecclesiastical
sense.. Its four churches, ancient St Tudno in a hollow on the northern
slopes of the Great Orme facing the Irish Sea (two miles from the modern
town) and the town churches of St George, Holy Trinity and the church of
Our Saviour, form an enclave of the See of Bangor. Llandudno is
surrounded on the landward side by Saint Asaph's parish of Llanrhos with
its four churches (SS Sennen and Hilary, together with St Paul's Craig y
Don, St David's Penrhynside and All Saints Deganwy). Much of the modern
town was formerly marshland without roads and the medieval Bishops of
Bangor, with their palace on the Great Orme, had to visit by boat
Tudno is said to have been one of the seven sons of King Seithenyn whose
legendary kingdom in Cardigan Bay was submerged by tidal activity. Each
son in reparation for their father's neglect (so it was seen) studied in
St. Dunawd's college at Bangor Iscoed. Later Tudno established the
Church on Cyngreawdr (the great rock - the Great Orme). The Ogof Llech
(a small cave on the headland, difficult of access, but with a clear
spring of water) was his cell. His ancient church has been heavily
restored many times until nothing remains from Tudno's day. The church
does however have a medieval carved wooden emblem high above the chancel
step depicting the five wounds of Christ - such an emblem surviving in
Wales is almost unique, only one other is known and it is in the
neighbouring parish of Llanrhos. [From the Church Guide book by T.F.
