The Church of Sainte-Magnance, whose origins date back to the 12th century, was rebuilt in the 16th century, and its bell tower was reworked in 1843 by the Avallonais architect Edme Tircuit.
The Gothic building used to be called St. Peter's, but history decided otherwise after the bones of St. Magnance were transferred there in the 13th century. According to legend, in 448, she was one of the five girls who travelled with the remains of the Bishop St. Germanus, who had died during his stay in Ravenna at the court of Galla Placidia. Before he died, he had asked for his body to be brought back to Auxerre. As she escorted the body of the deceased, Magnance died of exhaustion not far from their destination.
Nowadays, the church still houses the saint's tomb, adorned with remarkable bas-reliefs illustrating several scenes from her life. Originally polychrome, this carved masterpiece is an important example of the Burgundian Romanesque style.
