History of the Pentagon

• The Pentagon is the headquarters of the United States Department of Defense. It was dedicated on January 15, 1943 and it is the world's largest office building.

• It was built from 680,000 tons of sand and gravel dredged from the nearby Potomac River that were processed into 435,000 cubic yards (330,000 m³) of concrete and molded into the pentagon shape. Very little steel was used in its design due to the needs of the war effort.

• At five acres (20,000 m²), the central plaza in the Pentagon is the largest "no-salute, no-cover" area (where hats need not be worn and salutes are not required) in the world. The open space in the center is informally known as ground zero, a nickname originating during the Cold War when it was thought of as the most likely target of a nuclear missile. At the center of the plaza is the "Ground Zero Cafe," a snack bar. One 'legend' states that due to the heavy traffic into this cafe (evidenced by satellite imagery), Soviet intelligence concluded it was a center for highly secret research.
