Sts. Joseph, Teresa of Avila, and John of the Cross
Three statues in niches in the front façade of the St. Joseph Church. Depicted are the patron saint and the two most important saints of the Carmelites. The church was built by the Carmelites between 1627 and 1655, following the construction of their monastery.
The saints are:
Saint Joseph the husband of the Virgin Mary and the earthly father of Jesus Christ (in distinction to God, his "heavenly father") (Wikipedia).
