In Pictures: Cu Chi Tunnels — heroic underground feat

Cu Chi Tunnels in Ho Chi Minh City are considered a heroic feat and a marvel of Vietnam’s unique military arts. This “red address” symbolises the unyielding and indomitable spirit of the people in the "land of steel" during the country’s two major resistance wars.

The Cu Chi Tunnels relic site is located on Provincial Road 15, Phu Hiep Hamlet, Phu My Hung Commune, Cu Chi District (Ho Chi Minh City).

The tunnels were first constructed during the resistance war against the French and later reinforced during the war against the Americans. The underground network consists of multiple layers and levels, ranging from 3 to 12 metres deep, which stretch over 250 kilometres in length, winding through laterite and clay soil, while connecting with about 500 kilometres of surrounding trenches.

Within the tunnels were facilities such as weapons and food storage areas, water wells, Hoang Cam kitchens (smokeless stoves), command centres, surgery rooms, and engineering workshops — all capable of withstanding powerful bombings. The tunnel passages are extremely narrow, allowing only one person to pass at a time and requiring individuals to crouch low to move through.

The Cu Chi Tunnels encapsulate the ingenuity and adaptability of the Cu Chi military and civilians during decades of fierce and prolonged warfare in their quest for national independence, freedom, and unification.

Today, the Cu Chi Tunnels are preserved in two main areas including Ben Duoc (in Phu My Hung Commune) and Ben Dinh (in Nhuan Duc Commune).

Within Cu Chi, the secret underground shelters feature various designs, but are mainly hidden below the earth’s surface, with a single entrance just wide enough for a person’s shoulders and small ventilation holes for breathing. When sealed, these entrances were nearly undetectable to enemies walking above. (Photo: a currently preserved tunnel entrance at the Cu Chi Tunnels relic site).

The tunnel system spans multiple levels, ranging from 3 to 12 metres deep, and stretches over 250 kilometres with a maze-like layout, burrowed into the laterite-mixed clay soil, connecting with approximately 500 kilometres of surrounding trenches.
