Numerous stuccoes decorate the five domes, while the altars of the naves are in polychrome marble.
In the left nave there is an altar with a Crucifix and various marble panels with scenes from the Passion.
The altars are interspersed with valuable paintings including that of San Domenico che riceve lo Spirito Santo (St. Dominic Receiving the Holy Spirit) (18th century) and the Madonna del Rosario (Virgin Mary of the Rosary) by Vito D’Anna (1712). The main altar is formed of precious white and red marble.
Adjacent to it, there is a simulacrum of the Virgin Mary of the Rosary placed inside a ciborium made of gilded wood, a work attributed to Antonio Basile.
