Carcassonne Cathedral (French: Cathédrale Saint-Michel de Carcassonne) is a cathedral and designated national monument in Carcassonne, France. It is the seat of the Roman Catholic Bishop of Carcassonne and Narbonne.
The building was built in the thirteenth century as a parish church, dedicated to Saint Michael. Following war damage in the fourteenth century it was rebuilt as a fortified church.
In 1803 St. Michael's was elevated to cathedral status, replacing the earlier cathedral dedicated to Saints Nazarius and Celsus, now the Basilica of St. Nazaire and St. Celse.
St. Michael's is used by the Priestly Fraternity of St. Peter.[1]
