The tunnels of Cu Chi are an immense network of connecting tunnels located in Ho Chi Minh City (Saigon), Vietnam. They were the location of several military campaigns during the Vietnam War, and were the Viet Cong’s base of operations in 1968.
Communist forces began digging a network of tunnels in the late 1940s, during their war of independence from the French. Tunnels were often dug by hand, only a short distance at a time.
In heavily bombed areas, people spent much of their life underground, and the Cu Chi tunnels grew to house entire underground villages, in effect, with living quarters, kitchens, factories, hospitals and bomb shelters.
