The huge, 5-sided office building was built between September 11, 1941 and January 15, 1943. The design called for minimal use of steel (a wartime commodity) and was originally intended to be built at a different, roughly pentagonal site.
The Pentagon is located in Virginia, United States and is the Department of Defense's headquarters. The construction for the pentagon-shaped building began in 1941 and finished in 1943.
