After the coronation of Nominoë, the Breton ruler in 848, he promoted the bishop to archbishop and the city became the religious capital of Brittany ("la Métropole ecclésiastique de la Bretagne") and soon a cathedral replaced the existing church. This was destroyed by the Vikings in 1014. A Romanesque cathedral was then built. In the middle of the eleventh century there was a dispute between Pope Gregory VII and the Kings of France supported by the Archbishop of Tours over Dol-de-Bretagne filling the role of a bishopric and in 1199 the bishopric was withdrawn and jurisdiction was returned to the Archbishop of Tours. Nominoë's actions were effectively reversed.
