It is the seat of the confraternity of the same name. It has a single nave divided into six bays by transverse round arches and wooden roofing. Dating from the 17th century, it has a facade with a two-light ribbed bell tower and a single entrance portal, surmounted by a rectangular window. The church’s only furnishings: two small hanging stone stoups, ascribable to Sardinian stonemasons active in the 17th century, one decorated with baccellation and the other with a floral motif within a hexagon. The 18th-century high altar, made of limestone, is divided into three mirrors by four twisted columns of faux marble (recently repainted) on lozenge-decorated dadoes. On the central entablature can be recognized the coat of arms of the Aymerichs, lords of Mara Arbarei.
