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. General Brehon Somervell provided the major motivating power behind the project;[5] Colonel Leslie Groves was responsible for overseeing the project for the U.S. Army.
The Pentagon is the world's largest office building, with about 6,500,000 sq ft (600,000 m2) of space, of which 3,700,000 sq ft (340,000 m2) are used as offices.[6][7] Some 23,000 military and civilian employees,[7] and another 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 mi (28.2 km)[7] of corridors. The central five-acre (20,000 m2) pentagonal plaza is nicknamed "ground zero" on the presumption that it would be a prime target in a nuclear war.[8]
On 11 September 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.[9] 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.
The Pentagon is listed on the National Register of Historic Places and is a National Historic Landmark.[3]
Layout and facilities[edit]
The Pentagon building spans 28.7 acres (116,000 m2), and includes an additional 5.1 acres (21,000 m2) as a central courtyard.[10] Starting with the north side and moving clockwise, its five façade entrances are the Mall Terrace, the River Terrace, the Concourse (or Metro Station), the South Parking, and the Heliport.[11] On the north side of the building, the Mall Entrance, which also features a portico, leads out to a 600 ft (180 m) long terrace that is used for ceremonies. The River Entrance, which features a portico projecting out 20 ft (6.1 m), 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 landing dock was used until the late 1960s to ferry personnel between Bolling Air Force Base and the Pentagon.[10] The main entrance for visitors is on the southeast side, as are the Pentagon Metro station and the bus station. There is also a concourse on the southeast side of the second floor of the building, which contains a mini-shopping mall. The south parking lot adjoins the southwest facade, and the west side of the Pentagon faces Washington Boulevard.[citation needed]
The concentric rings are designated from the center out as "A" through "E" (with additional "F" and "G" rings in the basement). "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 (1 to 10) followed by a bay number (00 to 99), so office numbers range from 100 to 1099. These corridors radiate out from the central courtyard, with corridor 1 beginning with the Concourse's south end. Each numbered radial corridor intersects with the corresponding numbered group of offices (for example, corridor 5 divides the 500 series office block). There are a number of historical displays in the building, particularly in the "A" and "E" rings.[citation needed]
Floors in The Pentagon are lettered "B" for Basement and "M" for Mezzanine, both of which are below ground level. The concourse is on the second floor at the Metro entrance. Above ground floors are numbered 1 to 5. Room numbers are given as the floor, concentric ring, and office number (which is in turn the nearest corridor number followed by the bay number). Thus, office 2B315 is on the second floor, B ring, and nearest to corridor 3 (between corridors 2 and 3). One way to get to this office would be to go to the second floor, get to the A (innermost) ring, go to and take corridor 3, and then turn left on ring B to get to bay 15.[12] It is possible for a person to walk between any two points in The Pentagon in less than seven minutes.[13]
The complex includes eating and exercise facilities, and meditation and prayer rooms. Tours for the public were suspended after the 2001 attack.
Just south of The Pentagon are Pentagon City and Crystal City, extensive shopping, business, and high-density residential districts in Arlington. Arlington National Cemetery is to the north. The Pentagon is surrounded by the relatively complex Pentagon road network.[14]
The Pentagon has six Washington, DC ZIP Codes (despite its location in Virginia). The Secretary of Defense, the Joint Chiefs of Staff, and the four service branches each have their own ZIP Code.[15]
History[edit]
Background[edit]
Before The Pentagon was built, the United States Department of War was headquartered in the Munitions Building, a temporary structure erected during World War I along Constitution Avenue on the National Mall. The War Department, which was a civilian agency created to administer the U.S. Army, was spread out in additional temporary buildings on the National Mall, as well as dozens of other buildings in Washington, D.C., Maryland and Virginia. In the late 1930s, a new War Department Building was constructed at 21st and C Streets in Foggy Bottom but, upon completion, the new building did not solve the department's space problem and ended up being used by the Department of State.[16] When World War II broke out in Europe, the War Department rapidly expanded in anticipation that the United States would be drawn into the conflict. Secretary of War Henry L. Stimson found the situation unacceptable, with the Munitions Building overcrowded and the department spread out.[17][18]
Stimson told U.S. President Franklin D. Roosevelt in May 1941 that the War Department needed additional space. On 17 July 1941, a congressional hearing took place, organized by Virginia congressman Clifton Woodrum, regarding proposals for new War Department buildings. Woodrum pressed Brigadier General Eugene Reybold, who was representing the War Department at the hearing, for an "overall solution" to the department's "space problem" rather than building yet more temporary buildings. Reybold agreed to report back to the congressman within five days. The War Department called upon its construction chief, General Brehon Somervell, to come up with a plan.[19]
Planning[edit]
Government officials agreed that the War Department building, officially designated Federal Office Building No 1, should be constructed across the Potomac River, in Arlington County, Virginia. Requirements for the new building were that it be no more than four stories tall, and that it use a minimal amount of steel. The requirements meant that, instead of rising vertically, the building would be sprawling over a large area. Possible sites for the building included the Department of Agriculture's Arlington Experimental Farm, adjacent to Arlington National Cemetery, and the obsolete Hoover Field site.[20]
The site originally chosen was Arlington Farms which had a roughly pentagonal shape, so the building was planned accordingly as an irregular pentagon.[21] Concerned that the new building could obstruct the view of Washington, D.C., from Arlington Cemetery, President Roosevelt ended up selecting the Hoover Airport site instead.[22] The building retained its pentagonal layout because a major redesign at that stage would have been costly, and Roosevelt liked the design. Freed of the constraints of the asymmetric Arlington Farms site, it was modified into a regular pentagon which resembled the fortifications of the gunpowder age.[23]
On 28 July, Congress authorized funding for a new Department of War building in Arlington, which would house the entire department under one roof,[24] and President Roosevelt officially approved of the Hoover Airport site on 2 September.[25] While the project went through the approval process in late July 1941, Somervell selected the contractors, including John McShain, Inc. of Philadelphia, which had built Washington National Airport in Arlington, the Jefferson Memorial in Washington, and the National Naval Medical Center in Bethesda, Maryland, along with Wise Contracting Company, Inc. and Doyle and Russell, both from Virginia.[26] In addition to the Hoover Airport site and other government-owned land, construction of The Pentagon required an additional 287 acres (1.16 km2), which were acquired at a cost of $2.2 million (equivalent to $29.4 million in 2018[1]).[27] The Hell's Bottom neighborhood mainly numerous pawnshops, factories, approximately 150 homes, and other buildings around Columbia Pike, was also cleared to make way for The Pentagon.[28] Later, 300 acres (1.2 km2) of land were transferred to Arlington National Cemetery and to Fort Myer, leaving 280 acres (1.1 km2) for the Pentagon.[27]
Construction[edit]
Contracts totaling $31,100,000 (equivalent to $416 million in 2018[1]) were finalized with McShain and the other contractors on 11 September, and ground was broken for The Pentagon the same day.[29] Among the design requirements, Somervell required the structural design to accommodate floor loads of up to 150 pounds per square foot, which was done in case the building became a records storage facility at some time after the end of the current war.[25] A minimal amount of steel was used as it was in short supply during World War II. Instead, The Pentagon was built as a reinforced concrete structure, using 680,000 tons of sand dredged from the Potomac River, and a lagoon was created beneath The Pentagon's river entrance.[30] To minimize steel usage, concrete ramps were built rather than installing elevators.[31][32] Indiana limestone was used for the building's façade.[33]
Architectural and structural design work for The Pentagon proceeded simultaneously with construction, with initial drawings provided in early October 1941, and most of the design work completed by 1 June 1942. At times the construction work got ahead of the design, with different materials used than specified in the plans. Pressure to speed up design and construction intensified after the attack on Pearl Harbor on 7 December 1941, with Somervell demanding that 1,000,000 sq ft (9.3 ha) of space at The Pentagon be available for occupation by 1 April 1943.[34] David J. Witmer replaced Bergstrom as chief architect on 11 April after Bergstrom resigned due to charges, unrelated to The Pentagon project, of improper conduct while he was president of the American Institute of Architects.[35] Construction was completed 15 January 1943.[36]
Soil conditions of the site – on the Potomac River floodplain – presented challenges, as did the varying elevations across the site, which ranged from 10 to 40 feet (3.0–12.2 m) above sea level. Two retaining walls were built to compensate for the elevation variations, and cast-in-place piles were used to deal with the soil conditions.[37] Construction of The Pentagon was completed in approximately 16 months at a total cost of $83 million (equivalent to $1.11 billion in 2018[1]). The building is approximately 71 feet (22 m) tall, and each of the five sides of the building is 921 feet (281 m) long.[2]
The building was built one wing at a time; each wing was occupied as soon as it was completed, even as construction continued on the remaining wings.[citation needed]
The Pentagon was designed in accordance with the racial segregation laws in force in the state of Virginia at the time, with separate eating and lavatory accommodations for white and black persons; the sets of lavatories were side by side, and the dining areas for black persons were in the basement.[38][39] However, when Roosevelt visited the facility before its dedication, he ordered removal of the "Whites Only" signs, and The Pentagon became the only building in Virginia where segregation laws (which remained in force until 1965) were not enforced. The side by side sets of restrooms still exist, but are used by all.[39]
Incidents[edit]
Protests[edit]
The Pentagon became a focal point for protests against the Vietnam War during the late 1960s. A group of 2,500 women, organized by Women Strike for Peace, demonstrated outside of Secretary of Defense Robert S. McNamara's office at The Pentagon on 15 February 1967.[40] In May 1967, a group of 20 demonstrators held a sit-in outside the Joint Chiefs of Staff's office, which lasted four days before they were arrested.[41] In one of the better known incidents, on 21 October 1967, some 35,000 anti-war protesters organized by the National Mobilization Committee to End the War in Vietnam, gathered for a demonstration at the Defense Department (the "March on the Pentagon"), where they were confronted by some 2,500 armed soldiers. During the protest, a famous picture was taken, where George Harris placed carnations into the soldiers' gun barrels.[42] The march concluded with an attempt to "exorcise" the building.[citation needed]
On 19 May 1972, the Weather Underground Organization bombed a fourth-floor women's restroom, in "retaliation" for the Nixon administration's bombing of Hanoi in the final stages of the Vietnam War.[43]
On 17 March 2007, 4,000 to 15,000 people (estimates vary significantly) protested the Iraq War[44] by marching from the Lincoln Memorial to the Pentagon's north parking lot.[citation needed]
Renovation[edit]
From 1998 to 2011, The Pentagon was completely gutted and reconstructed in phases to bring it up to modern standards and improve security and efficiency. Asbestos was removed and all office windows sealed.[45]
As originally built, most Pentagon office space consisted of open bays which spanned an entire ring. These offices used cross-ventilation from operable windows instead of air conditioning for cooling. Gradually, bays were subdivided into private offices with many using window air conditioning units. With renovations now complete, the new space includes a return to open office bays, a new Universal Space Plan of standardized office furniture and partitions developed by Studios Architecture.[46]
11 September 2001 attacks[edit]
On 11 September 2001, coincidentally the 60th anniversary of The Pentagon's groundbreaking, a team of five al-Qaeda affiliated hijackers took control of American Airlines Flight 77, en route from Washington Dulles International Airport to Los Angeles International Airport, and deliberately crashed the Boeing 757 airliner into the western side of The Pentagon at 9:37 am EDT as part of the September 11, 2001 attacks. The impact of the plane severely damaged the outer ring of one wing of the building and caused its partial collapse.[47] At the time of the attacks, The Pentagon was under renovation and many offices were unoccupied, resulting in fewer casualties. Only 800 of 4,500 people who would have been in the area were there because of the work. Furthermore, the area hit, on the side of the Heliport facade, was the section best prepared for such an attack. The renovation there, improvements which resulted from the Oklahoma City bombing, had nearly been completed.[48][11][49]
It was the only area of The Pentagon with a sprinkler system, and it had been reconstructed with a web of steel columns and bars to withstand bomb blasts. The steel reinforcement, bolted together to form a continuous structure through all of The Pentagon's five floors, kept that section of the building from collapsing for 30 minutes—enough time for hundreds of people to crawl out to safety. The area struck by the plane also had blast-resistant windows—2 inches thick and 2,500 pounds each—that stayed intact during the crash and fire. It had fire doors that opened automatically and newly built exits that allowed people to get out.[49]
Contractors already involved with the renovation were given the added task of rebuilding the sections damaged in the attacks. This additional project was named the "Phoenix Project," and was charged with having the outermost offices of the damaged section occupied by 11 September 2002.[50][51][52]
When the damaged section of The Pentagon was repaired, a small indoor memorial and chapel were added at the point of impact. For the fifth anniversary of the 11 September 2001 attacks, a memorial of 184 beams of light shone up from the center courtyard of The Pentagon, one light for each victim of the attack. In addition, an American flag is hung each year on the side of The Pentagon damaged in the attacks, and the side of the building is illuminated at night with blue lights. After the attacks, plans were developed for an outdoor memorial, with construction underway in 2006. This Pentagon Memorial consists of a park on 2 acres (8,100 m2) of land, containing 184 benches, one dedicated to each victim. The benches are aligned along the line of Flight 77 according to the victims' ages, from 3 to 71. The park opened to the public on 11 September 2008.[53][54][55]
Hall of Heroes[edit]
On the building's main concourse is the Hall of Heroes, opened 1968[56] and dedicated to the more than 3,460 recipients of the Medal of Honor, the United States' highest military decoration.[57][58][59][note 1][62][63] The three versions of the Medal of Honor – Army, Sea Service (for the Marine Corps, Navy, and Coast Guard), and Air Force – are on display along with the names of recipients.[62] The Hall is also used for promotions, retirements, and other ceremonies.[64][65][66][67][68]

Notes[edit]
- ^ The Congressional Medal of Honor Society is so designated because that was the name it was given in an act of Congress that was signed into law by US President Dwight D. Eisenhower on 5 August 1958 as Title 36, Chapter 33 of the U.S. Code.[60] The law authorizing the society has since been transferred to Title 36, Chapter 405 of the U.S. Code.[61]
