The Pentagon

The Pentagon is the headquarters building of the United States Department of Defense. As a symbol of the U.S. military, the phrase The Pentagon is also often used as a metonym for the Department of Defense and its leadership. Located in Arlington County, Virginia, across the Potomac River from Washington, D.C., the building was designed by American architect George Bergstrom and built by contractor John McShain. Ground was broken on 11 September 1941, and the building was dedicated on 15 January 1943.

The Pentagon is the world's largest office building, with about 6.5 million square feet (150 acres; 60 ha) of floor space, of which 3.7 million sq ft (85 acres; 34 ha) are used as offices. Some 23,000 military and civilian employees, and another 3,000 non-defense support personnel, work in the Pentagon.

Quotes

 * We could never get a grip on it. It made you crazy. When you deal with the Pentagon, you go into a world of mirrors. It was a morass. Impossible to figure out.
