Located in the former Demilitarized Zone (DMZ) region of Quang Tri, Vinh Moc Tunnels were constructed during the Vietnam War as a refuge for villagers facing sustained aerial bombardment. Dug into the red basalt soil near the coast, the system developed into an underground settlement where residents could shelter for extended periods while maintaining essential community activities. The tunnels also supported logistical links to nearby Con Co Island, which held strategic importance during the conflict.

The tunnel network extends for approximately 1.7–2 km and is arranged across three underground levels, reaching depths of around 23 metres. Its passageways connect family living quarters with communal facilities, including a meeting hall, freshwater well, medical areas, a maternity room, storage spaces and a Hoang Cam kitchen designed to minimise visible smoke. Multiple entrances and exits connect the underground system with the surrounding hills and the coast, illustrating how the complex was designed to support both daily life and protection during wartime.

Today, sections of the tunnels and associated exhibition spaces preserve the story of the community that lived beneath the ground during the conflict. The site provides a tangible understanding of wartime living conditions, from narrow passageways and small family rooms to the communal facilities that sustained village life. Together with Hien Luong Bridge and the Ben Hai River, Vinh Moc Tunnels form an important part of Quang Tri’s historical landscape, commemorating civilian resilience and the enduring pursuit of peace.
