Hầm Chỉ huy Tác chiến T1

Located within the vast Thang Long Imperial Citadel complex, this secret underground bunker served as the high command center for the North Vietnamese Army during the Vietnam War. Built in 1967, it features thick concrete walls designed to withstand direct hits from B-52 bombers. Visitors can explore the preserved strategy rooms, communication equipment, and maps used by generals to coordinate air defense operations. The atmosphere is stark and somber, offering a chillingly authentic look into modern military history. It is often overlooked by tourists who only visit the ancient ruins above ground. This site is perfect for history buffs and those interested in the tactical side of the conflict.
