Dating back from 1549 and attributed to Diogo de Torralva, this church is one of the most unknown treasures of Lisbon, showing an erudite and original architectural plan with a Renaissance spirit. A few elements of particularity are the centralised plan and the semicircular porch that surrounds half of the building, covered by a rib vault with plenty of late Mannerist (end of the 17th Century) polychrome tile covering allusive to the Patron saint, with two tile altars with trempe l’oeil altarpieces. Three porticos give access to the inside, with a half-spherical stonework dome, with roof light, tile covering and three altars with Baroque gilded and blue painted wood carved altarpieces.
