Do you know that there is an underground tunnel built in the middle of the 19th century? And was abandoned after World War II. This tunnel is one hundred and fifty meters from the large Piazza del Plebiscito in the center of Naples. It is almost thirty meters underground. And leads to the Bourbon tunnel, consisting of 530 meters of giant passages, large caves, and narrow canals.
The tunnel was rediscovered only in the early 2000s after World War II. And according to the information. It was conceived as a retreat from the royal palace by the King of the Two Sicilies, Ferdinand II of Bourbon. But he was very much afraid that he would be overthrown by the populations of Sicily and Naples. Which were prone to unrest during the turbulent period of the Napoleonic war. Later the king ordered an escape tunnel in the volcanic rock under the streets of Naples. Which was built at the beginning of the 17th century. The tunnel was supposed to connect the royal palace with the military barracks in what is now Morelli Street. But Ferdinand II died in 1859 before the tunnel was completed. And from that period onwards the tunnel was abandoned.
The tunnel was not used until the early 1930s when it became a warehouse for confiscated and contraband vehicles. During World War II, the underground space was turned into a military hospital and a bomb shelter. After the war, the tunnels became a dumping ground for wartime debris. Construction waste, old TVs and refrigerators, wrecked cars and motorcycles, as well as fascist marble statues were dumped here. Then they sealed the tunnel and forgot about it. Now these underground passages, have been turned into a museum called Galleria Borbonica, where visitors can see interesting exhibitions of vintage cars and motorcycles, old shelters, ancient reservoirs, and much more. Although the place looks interesting but equally creepy.
