The Pentagon has a Washington, D.C. mailing address, but The Pentagon is actually located in Arlington County, Virginia, across the Potomac River from Washington, D.C. It is the headquarters of the United States Department of Defense. The Pentagon is the world's largest office building, with about 6,500,000 square feet of space, of which 3,700,000 square feet are used as offices. Some 23,000 military and civilian employees, plus 3,000 non-defense support personnel work in the Pentagon. It has five sides, five floors above ground, two basement levels, and five ring corridors per floor with a total of 17.5?miles of corridors. The central five-acre pentagonal plaza is nicknamed "ground zero" on the presumption that it would be a prime target in a nuclear war.
 On September 11, 2001, exactly 60 years after the building's construction began, American Airlines Flight 77 was hijacked and flown into the western side of the building, killing 189 people (59 victims and the five perpetrators on board the airliner, as well as 125 victims in the building), according to the 9/11 Commission Report. It was the first significant foreign attack on Washington's governmental facilities since the city was burned by the British during the War of 1812.
