Illumination's illusion in largest catacombs of the World [Pics]
Odessa underground tunnels (catacombs) were created nearly 200 years ago during mining of building materials that were used to build the city. Currently it is the maze of 2,500 kilometers with hundreds of entrances, exits, caves, and tunnels.
During the World War II, in 1941, when German and Romanian army occupied Odessa during the war, the Soviet Military headquarters gave the order to organize the partisan resistance. And Odessa catacombs were chosen as the camp for the unit of partisans. The provisions and weapons was enough there so the unit could stay underground for half a year. The partisan unit was fighting with nazi and Romanian army during all the period of occupation.
