In Vinh Moc - you'll find a very impressive temple complex. They are the remains of a North Vietnamese fishing village, where the people have built a tunnel complex to protect themselves against the American bombing. Literally, the village went underground. It offered protection to more than 90 families. The tunnel complex has three levels. The majority of the tunnels is open to visitors and is kept in their original state (with the exception of the recent addition of electric lighting).
The tunnels were used not only for civilian purposes (the distinction between civilians and Vietcong is a dim area), but were also used to transport weapons and other equipment. These were brought to Con Co Island, a base off the North Vietnamese coast near Vinh Moc in the South China Sea.
The tour usually starts at the museum, which is above the ground. There are objects and photographs on displays. There is also a watch, which is a gift from the GDR.
Then begins the real visit to the tunnels. The tunnels are situated at a depth of 11 to 20 meters. You'll pass the "family quarters" - really just niches on the side of the main tunnel, with barely enough room for three people and zero privacy. They also show you larger dwellings, which were used for meetings, storage, and as a hospital. Nowadays, there are life-sized puppets, to make it clear for the tourists.
Suddenly you stand again in daylight, right by the sea, just above a beach. This output is well camouflaged. This output was at night to receive weapons and other supplies, which were sent via Con Co Island. Then you go back in and finally you'll get out at one of the ground-level exits.
During the approximately four years they lived under the ground, there were 17 babies born in the "tunnel hospital." In principle, these babies would only see the light when the war was over.
