The church consists of two juxtapositioned rectangular spaces, comprising a single nave and presbytery, with sacristy abutting, storage spaces, lateral courts and corridor. The horizontal articulated volumes and differently covered with tile. The frontispiece, which faces the south, consists of corner pilasters crowned by a triangular pediment, with a tympanum marked by elliptic oculus. The portico is framed by Manueline decoration, with double arched doors with niche, framed by relief pilasters, ornamentally decorated, with the sculptures of the "Anjo da Anunciação" ("Angel of the Annuciation") and "Virgem" ("Mary") in niche, united by Roman arch and flourishes in the jambs. Above this is a lintel, surmounted by two armillary spheres and cross of the Order of Christ. In the tympanum, in low relief is the figure of "Nossa Senhora da Misericórdia" ("Our Lady of the Misericórdia"). Lateral windows, framed by segmented columns, complete the facade, with a lot of decoration, including images of the saints.
