A very active religious community uses this beautiful and unusual church, built by the Pénitents Noirs in 1625 and altered during the 19th century. The circular choir and nave are painted blue-grey with white bas-reliefs depicting christian virtues and scenes from the New Testament. Above the altar, the only painting in the church is Saint Helen finding the Holy Cross in Jerusalem (1788). A relic of the Holy Cross is kept in a glass case near the entrance, along with a statue of Saint Jerôme. About one hundred candles are burnt here every day.
