Auch Cathedral (French: Basilique Cathédrale Sainte-Marie d'Auch) is a Roman Catholic church located in the town of Auch in the Midi-Pyrénées, France. It is a national monument, and is the seat of the Archbishopric of Auch. Under the Concordat of 1801, the ecclesiastical office was dissolved and annexed to the Diocese of Agen, but re-established in 1822. It was granted the status of a basilica minor on 25 April 1928.[1] The cathedral contains a suite of 18 Renaissance stained glass windows by Arnaud de Moles.
