The previous cathedral was built here in the 12th century. Little remains of this building apart from a Romanesque arm and the crossing of the transept. The cloisters date from the 13th century. Otherwise the church was entirely rebuilt starting from 1450, in the Flamboyant style, and work was still not completed in 1568, when during the French Wars of Religion, from which this region suffered particularly severely, the building was sacked by Protestants, causing such serious damage that the nave had afterwards to be entirely rebuilt.
Lack of resources meant that a complete rebuilding has never been possible. The heavy appearance of the tower, for example, results from the lack of the spire intended to finish it, the present dome constituting a more economical substitute.
The interior is made striking by its lack of decoration and by the wooden ceiling, completed in 1927.
