And, the answer for the the question is :
[STC00627] Odessa, which is located in Ukraine, is home to an enormous network of man-made tunnels that combine to cover a distance of more than 1,500 miles in total. Since the 18th and 19th centuries, when they were constructed, the catacombs have been an essential part of the tale of the development of this Eastern European city. During World War I, the never-ending maze was used as a hiding spot for Soviet revolutionaries and as a refuge for citizens fleeing the carnage. During the time of the Cold War, the underground tunnels were converted into bunkers so that people might be protected from the threat of nuclear conflict. Today you’ll mostly find them empty — though some locals use them as cellars for aging cognac and wine.
