Building D67

Building D67 may look unassuming, but this grey concrete structure hides a wartime secret. Once the nerve center of North Vietnam’s military command, its underground tunnels still echo with history. Old radios, war maps, and dimly lit control rooms remain untouched—like time froze during the conflict. Standing here, you can almost hear the urgency in the voices, feel the tension in the walls. This is history not read, but lived.
