Galleria Borbonica

The Bourbon Tunnel, Tunnel Borbonico or Bourbon Gallery is an ancient underground passage, constructed for military purposes to connect the Royal Palace to military barracks in Naples, Italy. The monarchy in the era of King Ferdinand II of Bourbon was fearful of the revolution-prone populace of Naples. Errico Alvino was commissioned to construct a military passage for troops connecting the Royal Palace of Naples to Via Morelli, boring underneath the hill of Pizzofalcone and reaching the quartiere San Ferdinando, but also connecting to other tunnels and aqueducts, including the old Carmignano aqueduct. The monarchy would also not have been ignorant that the Viceroy of Naples in 1647 had nearly been trapped in this urban Royal Palace, and only by luck was able to flee to a nearby convent to escape angry crowds during the Revolt of Masaniello, thus the tunnel could also serve as an escape route for its royal inhabitants. Two years after it was begun, the fall of the Bourbon dynasty meant that construction came to a halt. During the Second World War, the tunnel was used as a shelter during bombardments.
