Hospital Cave
Its name is fairly self-explanatory, as this large man-made underground cave was once used as a secret building to attend to the wounded during the American War. Later on, it was also used as a safe space for the Viet Cong and wasn't abandoned until 1975. The huge cave covers three storeys and includes an operating theatre, a natural cavern used as a cinema, and even a swimming pool.
