The seat of the ancient bishopric of Dol, the Saint-Samson cathedral dates to the 13th-century and is primarily Gothic in style with both Norman and English influences. It was built on the site of an old church where Nominoë was crowned as the first king of Brittany in 850. This old church was replaced by a Romanesque style cathedral which was in turn destroyed in 1203 by the soldiers of Jean sans Terre and little is left of that building today. From Saint Samson in the 6th century to Monseigneur de Hercé, shot at Vannes in 1795, more than 80 bishops have occupied the bishopric of Dol. Since 1880 the Archbishop of Rennes is the Archbishop of Rennes, Dol and Saint-Malo. The cathedral has retained little of the old furnishings as in 1742 the cathedral chapter decided to get rid of all the old bishop's tombs and relaid the choir paving and in 1793 the rood screen which had separated the choir from the nave was demolished and was replaced by an iron grill on the orders of the zealots of the revolution.
