The Pentagon is often portrayed alongside the White House in Hollywood action movies, such as Top Gun and Iron Man.
For those of you unfamiliar with the building, it is the military headquarters of the United States.
The leader of this department is the Secretary of Defense, who is nominated by and reports directly to the US President.
But where is the iconic building situated – is it near the White House?
Here is all you need to know.
Where is the Pentagon in relation to the White House?
The White House is located at 1600 Pennsylvania Avenue in Washington, D.C., the capital of the United States.
The Washington Monument, the Capitol Building, the Jefferson Memorial, the Pentagon, and the Lincoln Memorial are also in the area.
The Pentagon is situated just outside Washington DC, in Arlington County, Virginia.
The building was designed by American architect George Bergstrom and built by contractor John McShain, and cost more than $900 million (around £652.6 million) to build in today’s money.
The architects and designers came up with a unique pentagonal plan for the building so that would maximize the building site’s odd dimensions – which is how it got its name.
It is the world’s largest office building, with about 6.5 million square feet of floor space.
The Pentagon is twice the size of the Merchandise Mart in Chicago, has more than twice the floor space of the Empire State Building, and the US Capitol could fit into any one of its five wedge-shaped sections.
Around 23,000 employees, and another 3,000 non-defense support personnel, work in the Pentagon.
The building has nearly 17 and a half miles of corridor, yet – due to its unique design – movement between any two opposite points takes as little as seven minutes.
There are 19 escalators, 131 stairways, 284 restrooms, 691 water fountains, and enough telephone wire in the building to wrap around the world four and a half times.
