Vinh Moc Tunnels - a place well-known as an underground village constructed to avoid bombardments during the American War (1965-1966).

The spectacular tunnel network stands as a testament to the endurance, wisdom and bravery of the local people in their fight for independence. The tunnels used to be thousands of meters long. But now there remain only 1,700m. This underground network is linked with 13 doors (seven opening to the sea and six to the hills). The structure is divided into three layers, the deepest being 23m underground. They are connected by a 768m main axis that is 1.6 to 1.8m high and 1.2 to 1.5m wide. It is linked to the sea by seven exits, which also function as ventilators and to a nearby hill by another six.

Along the two sides of the main axis are housing chambers. There is also a large meeting hall with a seating capacity of 50 to 80 people, which was used for meetings, movies, art performances, surgeries, and even the delivery of babies (17 were born here). There are also four air wells, two watch stations and three water wells. The village featured unique Hoang Cam stoves, named after the general who invented the store to allow for underground cooking without emitting smoke, thus evading the discovery by bombers.

Before entering the tunnels, visitors are shown the displays of that brutal period in Vietnam's history by some photos. They provide a sharp contrast for the vitality of the local people in during war time, celebrating on the victory day.

The war forced many people to either leave their villages or live beneath the ground. Vinh Moc residents opted for the second solution. A few would imagine that the rubber and pepper tree plantations today used to be a fierce battleground from 1966-1972 when Vinh Moc was a place to pass food and ammunitions to Con Co Island.

The area underwent tens of thousands of tonnes of bombs by U.S warplanes. The invaders wanted to return the area to the "stone age" and launched a destructive war there. It was estimated that local residents endured the equivalent of 500 heavy rockets per day.

In 1976, the Ministry of Culture and Information recognised Vinh Moc Tunnels as national heritage site and included it in a list of especially important historical sites. To ensure security for visitors, the tunnels were restored with reinforced concrete and internal lightening.
