The church has a single nave, which has preserved a superb majolica pavement by Neapolitan Nicolo Sarzana. From the women's' tribune of the annexed convent, once reserved for the enclosed order of nuns, you have a magnificent view of the Church and you can marvel at the intricately worked small wrought iron grill . The apse is decorated with some most attractive stucco by Bartolomeo Sanseverino.
