The present church was built after the 1693 earthquake. Previously the site had a church dedicated to St Thomas of Canterbury and a monastery dedicated to San Giuliano, which became a hospital dedicated to San Marco. The church in dedicated to St Cajetan and was staffed by his Theatine order, who lived in a small adjacent monastery. The tall narrow facade has simple elements but is decorated just above the door and in a frieze along the tympanum.^[1]
