 |
| This military masterpiece was built from 1965 to 1967, deep underground in coastal sand, at an average depth of 3-5m, up to 10m in some places, with a solid layer of laterite soil, helping to avoid being flattened by bombs. (Photo: Zing) |
 |
| This system has a checkerboard structure, consisting of hundreds of small tunnels connected by horizontal tunnels, with secret lids carefully camouflaged with grass, straw, coal pits, water wells or cowsheds. (Photo: iVIVU) |
 |
| The center of the tunnel is located right under Thach Tan communal house - the place considered the "heart of the resistance" - which was once destroyed by the enemy using 4 tanks but still stands firm with time. (Photo: iVIVU) |
 |
| Inside the tunnels, there are full facilities for combat and living such as command bunkers, meeting bunkers, food warehouses, first aid stations, communication stations and shelters for hundreds of people. (Photo: Lam Dong Newspaper) |
 |
| During its 10 years of existence, the tunnel helped the people and army of Ky Anh commune organize more than 1,000 guerrilla battles, destroying more than 3,700 American and Republic of Vietnam soldiers, and shooting down 30 tanks and 23 planes. (Photo: iVIVU) |
 |
| After the war, Ky Anh tunnels were largely buried, but now about 200m have been restored with a traditional house displaying 160 artifacts and historical documents, helping visitors understand the resistance period. (Photo: Zing) |

| Recognized as a national historical relic in 1997, Ky Anh tunnels became a heroic symbol of patriotism, creativity and bravery of the army and people of Quang Nam. (Photo: iVIVU) |
