Built in the 17th century owed to John Vardon, an Irishman and guard at the University, replacing the old ruined oratory that existed on the same street.
Baroque style architecture, the galilee consisting of a triple granite arcade with balustrade terrace and a panel of tiles from the workshop of Oliveira Bernardes. Inside stand out: afresco paintings (late-mannerists), tile panels and in the main chapel, the eighteenth-century gilded altarpiece.
