Church of S. Maria della Catena, also known as the church of S. Gaetano. Il Piaggia believes that the temple was built in the Aragonese era and was restored in 1621. In 1717 the Jesuits settled in the church after having founded a company of lay people in a nearby house. Important works, after 1718, renewed its appearance. The building, reduced to the essential structures with traces of decoration, has a single nave with a quadrangular apse covered by an elegant dome with a pennant. The four side altars were housed in niches alternating with pilasters, with rich rococo stucco decoration of which few remains. The facade is unique, with a rococo door surmounted by a bare window. The side door, with paraste and capitals Corinthian, is of refined Renaissance workmanship. The building, as a whole, probably dates from the late Renaissance and could accept the date of 1621 reported by Piaggia. At the high altar was the painting of the Madonna della Catena, now preserved in the church of Addolorata al Capo. The polychrome statue of S. Gaetano is located in the church of S. Caterina d’Alessandria.
