The church was dedicated to Saint Joseph, stepfather of Jesus, and so was funded naturally by the Confraternity of the Carpenters.
1663 the church was redesigned in opulent Baroque style and in 1886 it underwent another restoration.
At the altar on the left hand side is a Nativity by Carlo Maratta that dates to 1661.
