Historical landmark
Military Hospital Cave
Cat Hai, Hai Phong
Wartime hospital hollowed into limestone, three concrete floors of operating rooms, a cinema and guard posts hidden inside a mountain.
This guide to Military Hospital Cave near Ha Long Bay describes a fully functioning wartime hospital that Vietnamese military engineers hollowed into limestone between 1963 and 1965, hidden two hundred meters inside the mountain. It walks through the operating theaters, wards and even a cinema cut into raw rock, built to keep the wounded and sheltering islanders going through years of American bombing. Two doors, one facing east and one west, were built so no single airstrike could seal everyone inside.
