In ancient times, Montferrand was an important customs post on the Via Tolosa, which linked Toulouse and Narbonne. The Gallo-Roman city then covered nearly 12 ha. Archaeological excavations have brought to light a number of remains such as thermal baths, an early Christian church, and 52 stone sarcophagi as well as tombs.
Probably initially just a simple halt, Montferrand, then called ‘Elusio’, quickly became an agglomeration where goods arrived from the Roman world and even beyond. Archaeological excavations have revealed thermal baths and necropolises from the 6th century, totally nearly 140 burials. The basilica surprises us with a small oriental feature in its oversized apse.
In the Middle Ages, the city was besieged by Simon de Montfort and the castle was destroyed. A 14th century door is, however, still visible.
Today, from the top of the village, you can enjoy a superb panorama of the Pyrenees or the Montagne Noire, see the old Aéropostale lighthouse and the three churches!
