This chapel, built in 1734 by the brotherhood of white penitents, bears the title of Saint Blaise, patron saint of hemp carders. Great healer and bishop of Sebaste in Armenia, he was martyred during the reign of Diocletian and died in 316.

The tympanum of the door presents the remains of a sculpture mutilated during the revolution, representing two penitent monks kneeling at the foot of a cross. The building has two architectural elements from the 18th century listed in the inventory of historical monuments: a decorated and carved wooden ceiling, and a wrought iron platform grid.

The chapel surmounts an isolated rock, originally occupied by a building which still remains enigmatic, perhaps a medieval tower or a defensive element erected during the Wars of Religion in the 16th century.

During the revolutionary period, the chapel served as a Republican meeting room. Today it can host baptisms, religious ceremonies and cultural events.
