You'll probably see Mirepoix Cathedral across town before you actually find this incredible building. Step inside if the doors are open or just appreciate the facade from outside.
Located in Mirepoix, this principal church is well worth a visit. But you'll find loads more to check out in this area. Maison des Consuls, Château de Lagarde, and Merovingian Necropolis of Tabariane are within easy reach of Mirepoix Cathedral.
