The tunnels were never fully completed as a royal passage before the end of the Bourbon monarchy.
The complex served as a judicial depot for seized and abandoned vehicles for many years post-WWII.
Evidence of ancient Greek and Roman water management systems, including parts of the Serino aqueduct, is visible within the limestone walls.
The tunnels were utilized as a fallout shelter during Allied bombings, and remnants of graffiti and personal belongings from that era remain intact.
The debris clearing process for the site removed thousands of cubic meters of rubble that had accumulated since the war.

Galleria Borbonica is a subterranean passage commissioned by King Ferdinand II of Bourbon in 1853, originally intended as a military escape route and a connection between the Royal Palace and the sea. The Vico Grottone entrance provides access to this extensive network of tunnels, which features historical water conduits, air-raid shelters, and antique vehicles. During World War II, the site served as an emergency hospital and a refuge for citizens fleeing aerial bombardments. The tunnels house a substantial collection of abandoned cars, motorcycles, and Vespa scooters from the mid-20th century. Visitors explore sections of the ancient Bolla aqueduct and Roman-era cisterns intertwined with the Bourbon-era engineering. The site maintains a consistent temperature throughout the year due to its subterranean location. Excavations have revealed archaeological strata spanning from the Greek era to the modern period. Guided tours are necessary to access the complex safely and gain context regarding the site's complex structural history.
