Viengxay caves, Show cave system in Hūaphan, Laos.
The Viengxay cave network extends through limestone mountains, featuring multiple chambers and tunnels carved by natural processes over extensive periods.
During the Second Indochina War, these caves provided shelter for 23,000 people of the Pathet Lao forces, protecting them from American bombing campaigns.
The cave system demonstrates the determination of Laotian people, containing remains of wartime facilities including hospitals, schools, theaters, and administrative offices.
Visitors can access the cave complex through guided tours that provide detailed information about the site's history and geological formations.
The network includes 480 individual caves that functioned as an underground city, complete with bakeries, shops, and medical facilities during wartime.
