The cars were discovered only recently.
Under the Italian city of Naples has a whole system of underground tunnels located at a depth of about thirty metres and their total length is measured a few hundred of those meters.
Initially, tunnels were built during the reign of the monarch Ferdinand II. He was prone to paranoia and is constantly in a state of fear for their own lives. The tunnels were to save his life, if necessary to escape. By the end of world war II, the tunnels were forgotten and mothballed them.
And only in the new Millennium underground passages again began to explore. They had found a large number of old cars. The catacombs became a place of storage of seized smuggled cars. Today, the tunnels are referred to as gallery “Borbonica” and it can visit anyone.
