Hospital Cave, as the name suggests, is a secret hospital built inside a mountain on Cat Ba island, about 10 kilometers from Cat Ba town and close to Cat Ba national park. Constructed between 1963 and 1965, during the height of the Vietnam War, the cave was designed to withstand heavy bombing while providing a safe place for medical care and military operations.

The cave was carefully carved out of solid limestone, making it virtually indestructible against air raids. Inside, it could house hundreds of people, including wounded soldiers who needed treatment and military leaders who used it for planning sessions. Beyond its medical role, the cave also functioned as a secure hideout, giving the Vietnamese army a huge strategic advantage.
