The Cu Chi tunnels are a vast underground network of tunnels in Vietnam, outside Ho Chih Minh City (nee Saigon). It was used by guerilla fighters of the Viet Minh in the 1940s against French forces, and the Viet Cong in the 1960s and 1970s against South Vietnam and the United States forces during the Vietnam War.
