The tunnels of Cu Chi are an immense network of connecting underground tunnels located in the CuChi district of Ho Chi Minh City (Saigon), Vietnam, and are part of a much larger network of tunnels that underlie much of the country. The Cu Chi tunnels were the location of several military campaigns during the Vietnam War, and were the Viet Cong’s base of operations for the Tet Offensive in 1968.
The tunnels were used by Viet Cong guerrillas as hiding spots during combat, as well as serving as communication and supply routes, hospitals, food and weapon caches and living quarters for numerous guerrilla fighters. The tunnel systems were of great importance to the Viet Cong in their resistance to American forces, and helped achieve ultimate military success.
The Cu Chi Tunnels are a network of underground passageways that run to more than 120 miles (200 kilometers) in total length in this area alone. Work by the Viet Cong commenced in 1948 as a means of shelter from the French air attacks during the Indochina conflict.
The network provided vital access and strategic control over the large rural area surrounding Ho Chi Minh City; over the following two decades the tunnels became a complex underground city including hospitals, defenses and living quarters. This meant despite all the bombings in the area many of the local people could still continue to live underground. In its prime and at its most impressive the Cu Chi Tunnels stretched from the southern Vietnamese capital all the way to the Cambodian border to the west, and in places was dug to 3 stories deep.
Much of the original tunnel system was destroyed in bombing raids during the 1970s but existing parts have been restored and opened as a poignant and fascinating reminder.
