The world’s largest office building, the Pentagon was synonymous with the Department of Defense and a symbol of American military might. Exactly 60 years before the September 2001 attacks, on September 11, 1941, ground was broken in Arlington Country, Virginia, for a huge new building to house the War Department, forerunner of today’s Department of Defense. The department was then operating from 17 separate buildings in Washington. At certain periods 13,000 people worked on the project. Originally, plans called for three floors, but as the military prepared for war after the attack on Pearl Harbor, two more floors were added.
