De Marinis Palace, designed in the 19th century by architect Raffaele Comes, is one of the most remarkable buildings along Traetta Street. It helps to shape the area's identity.

The palace belonged to Mauro De Marinis (1820–1880), a respected patriot from a prominent family of jurists. It stands out for its elegant design and refined balance of its interior spaces.

The entrance hall is particularly striking, with a graceful vestibule and a grand staircase that leads to the richly decorated rooms on the main floor. Each detail reflects the refined taste of the 19th century, making this residence a fine example of that period's architecture and aesthetic sensibilities.
