The church has a single nave, which still has a superb majolica pavement, by Neapolitan Nicolo Sarzana; sadly, however, it is very damaged. From the women's tribune, once reserved for the cloistered order of nuns of the adjoining convent (which has since disappeared), you have a magnificent view of the church and can marvel at the ornate little wrought-iron grill. The apse is decorated with fine stuccowork by Bartolomeo Sanseverino.
