François-Bérenger Saunière (11 April 1852 – 22 January 1917) was a French Catholic priest in the village of Rennes-le-Château, in the Aude region. He was a central figure in the conspiracy theories surrounding the village, which form the basis of several documentaries and books such as the 1982 Holy Blood, Holy Grail by Michael Baigent, Richard Leigh, and Henry Lincoln. Elements of these theories were later used by Dan Brown in his best-selling 2003 novel The Da Vinci Code, in which the fictional character Jacques Saunière is named after the priest.Saunière served in Rennes-le-Château from 1885 until he was transferred to another village in 1909 by his bishop. He declined this nomination and subsequently resigned. From 1909 until his death in 1917, he was a non-stipendiary Free Priest (an independent priest without a parish, who did not receive any salary from the church because of suspension), and who from 1910 celebrated Mass at an altar constructed in a special conservatory by his Villa Bethania. Saunière's refusal to leave Rennes-le-Château to continue his priesthood in another parish incurred permanent suspension. The epitaph on Saunière's original 1917 gravestone read "priest of Rennes-le-Château 1885-1917".
