The Pentagon is a building located outside of Washington, DC that houses the US Department of Defense. It is one of the largest office buildings in the world.
The Pentagon was built in 1943 in Arlington, Virginia, across the Potomac River from Washington. It occupies some 6.5 million square feet and houses roughly 23,000 civilian and military employees. During the 9/11 terrorist attacks, the hijacked American Airlines Flight 77 crashed into the side of the building, killing 189 people.
