This video explores the secretive world of the Pentagon, America's military headquarters and the largest low-rise office building on Earth. Discover the hidden aspects of this five-sided fortress, including its forgotten tunnels, sealed war rooms, and 17 miles of corridors that remain inaccessible to the public. Learn about the Pentagon's rapid construction, the classified areas in its deeper levels, and how its architectural design serves strategic purposes of control, movement, and defense. The 13-minute documentary also covers historical events like the Pentagon Papers controversy and reveals details about internal surveillance systems and abandoned access tunnels, explaining why this massive structure remains one of America's most restricted facilities despite housing thousands of workers daily.
