Montbrison sur Lez

The village lies at the crossroads of ancient Roman roads.
At the beginning of the 1st century, vast buildings were erected here. In the 11th century, Cluny monks built a large church and priory on the remains of a Carolingian church and monastery, which had themselves been built on the site of an ancient Gallo-Roman villa and a small sanctuary dedicated to Mercury and Jupiter.
By the end of the 14th century, everything had almost collapsed, and only a small 11th-century chapel, rebuilt in the 15th century, remained. Pillar bases are visible on the site, testifying to the importance of the former Cluniac priory.
On the southern flank of the 11th-century medieval village, an orientation table offers a magnificent view of the Ventoux, the Monts du Vivarais and the whole of Haute-Provence. The village church, built during the French Revolution in 1791, houses a small bell from the Prieuré. To the right of the porch, in a shed, a large bell cast in 1875, called Claire Immaculée, still awaits its steeple. On the banks of the Lez, in Pontaujard, the remains of one of the Drôme's few Roman bridges, near a former seigniorial residence owned by the Hospitaliers.
