About The Pentagon in brief
The Pentagon is the headquarters building of the United States Department of Defense. 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. The Pentagon is listed on the National Register of Historic Places and is a National Historic Landmark. On 11 September 2001, exactly sixty 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. The complex includes eating and exercise facilities, meditation and prayer rooms, and extensive high-density shopping, business, and residential districts in Arlington and Crystal City. Just July 2020, the Pentagon will have its own ZIP Code, and the four branches of the Joint Chiefs of Staff will have their own service codes, as well as the Pentagon City ZIP Code. It is possible for a person to walk between any two points in the Pentagon in less than seven minutes. The central five-acre pentagonal plaza is nicknamed \”ground zero\” on the presumption that it would be a prime target in a nuclear war. 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. Some 23,000 military and civilian employees, and another 3,000 non-defense support personnel, work in the building. The main entrance for visitors is on the southeast side, as are the Pentagon Metro station and the bus station.
The south parking lot adjoins the southwest facade, and the westside of the Pentagon faces Washington Boulevard. A landing dock was used until the late 1960s to ferry personnel between Bolling Air Force Base and the Pentagon. The Pentagon building spans 28. 7 acres, and includes an additional 5. 1 acres as a central courtyard. Starting with the north side and moving clockwise, its five façade entrances are the Mall Terrace, the River Terrace,. the Concourse, the South Parking, andThe Heliport. The River Entrance, which features a portico projecting out twenty feet, is on the northeast side, overlooking the lagoon and facing Washington. A stepped terrace on the River entrance leads down to the Lagoon; and a stepping terrace leads to a 600-foot-long terrace that is used for ceremonies. The concourse is on the second floor at the Metro entrance, and there is also a mini-shopping mall on the south side. There are a number of historical displays in theBuilding, particularly in the \”A\” and \”E\” rings. The concentric rings are designated from the center out as \”A\’ through \”E\’. \”E” Ring offices are the only ones with outside views and are generally occupied by senior officials. Office numbers go clockwise around each of the rings, and have two parts: a nearest-corridor number followed by a bay number, so office numbers range from 100 to 1099.
