Saint-Claude Cathedral

Saint-Claude Cathedral is a Roman Catholic cathedral dedicated to Saint Peter, Saint Paul and Saint Andrew, and a national monument of France, located in the town of Saint-Claude.

The present cathedral was previously the church of the former Condat Abbey, which with the village that grew up round it soon acquired the name of Saint-Oyand or Saint-Oyend after Saint Eugendus, fourth abbot and a popular saint. In 687 Saint Claudius resigned as Bishop of Besançon and became the twelfth abbot. After he died, in 696, his grave became a very popular pilgrimage centre, to the extent that by the thirteenth century, the name "Saint-Claude" had become more used than that of "Saint-Oyand", which it superseded.
