16th-century baroque, stations of the cross, wooden stalls for penitents.
The statutes of the Brotherhood of the Black Penitents were founded under the title of the Nativity of Saint John the Baptist and Saint John the Beheaded. The Black Penitents looked after the sick, the poor, the washing of the dead and burials.
Exterior: the chapel is rectangular in shape. The baroque style façade is topped by a broken pediment and a pretty volute bell tower
The interior: on the left, the stalls of the penitents, a statue of Saint John the Baptist in his processional chair decorated with twisted columns in baroque style. In the centre, the altarpiece dedicated to the Virgin and Child surrounded by St John the Baptist and St Michael the Archangel. An anonymous 16th century painting restored by the fresco artist Guy Ceppa in 1979. Under the altar, a 17th century polychrome wooden recumbent Christ.
The Way of the Cross: dates from the Sardinian restoration (1814-1860). In the Crypt were kept the reserves of grain lent by the penitents to peasants whose harvests had failed. This was the Mont Piété Frumentaire or Granitique.
