The Pentagon
From Wikipedia, the free encyclopedia
The Pentagon is the headquarters of the
United States Department of Defense, located at 48 N. Rotary Road,
Arlington, Virginia 22211 (
Map). Its mailing address is "Washington, DC 20301." As a symbol of the US military, "the Pentagon" is often used
metonymically to refer to the Department of Defense rather than the building itself. Those who work within its walls often simply call it
the Building.[

The building was dedicated on
January 15,
1943. It is the highest-capacity
office building in the world and one of the
world's largest buildings in terms of floor area. It houses approximately 23,000 military and civilian employees and about 3,000 non-defense support personnel. It has five sides, five floors above ground (plus two basement levels), and five ring corridors per floor with a total of 17.5 miles (28 km) of corridors.
At five acres (20,000 m²), the central plaza in the Pentagon is the world's largest "no-
salute, no-
cover" area (an area exempt from the normal rule that, when out of doors, U.S. military personnel must wear hats and salute superior officers). The open space in the center is informally known as "
ground zero," a nickname originating during the
Cold War when it was thought of as the most likely target of a
nuclear missile. At the center of this plaza is the "Ground Zero Cafe," a snack bar.
Just south of the Pentagon are
Pentagon City and
Crystal City, extensive shopping and high-density residential districts in Arlington.
Arlington National Cemetery is to the north. The
Washington Metro Pentagon station is also located at the Pentagon, on the
Blue and
Yellow Lines. The Pentagon is surrounded by the complex
Pentagon road network, has also been known to locals as "The Mixing Bowl."
