The Church of Sillans-la-Cascade is under the patronage of the relics of Saint-Etienne, a martyr whose feast is celebrated on 3 August. The church preserves a relic of the first martyr, Saint-Etienne. It was brought in the end of the 12th century by a member of the noble family of Pontevès returning from a crusade. It succeeded an ancient chapel dedicated to Saint-Laurent, published in 1079 in a bull of Pope Gregory VI. It still existed in the beginning of the 19th century.
