Pre-Norman Establishment
The present building has sections that date from Anglo-Saxon times. In the ninth century the wooden church formerly on the site was rebuilt in stone. This indicates the importance of the cult of Saint Gwynllyw and the wealth of his shrine as stone buildings were unusual in Wales at this point. Part of this building is now incorporated into St Woolos cathedral as the Galilee chapel now at the west end of the Cathedral.
Circa 1050 the church was attacked by pirates and left in ruins.
