The Paysan abbot, was made priest of Menil Gondouin in 1873. He decorated the inside and outside of the church himself. Between 1873 and 1921, the ground and the walls are covered with saint writings and quotes painted or engraved. In order to bring the decoration to perfection, the abbot brought in many statues, paintings, creeds. His church became "alive and talking", organised like a huge reliquary, a Christian museum, unique.
