"The Pentagon is three in one. It is a building, an institution, and a symbol. As a building, it is one of the wonders of the modem world, an immense and efficient structure created in a mere 16 months between September 1941 and January 1943 – a remarkable feat of conception, design, and construction. As an institution, it is the nerve center of the U.S. military establishment. To the nation and world it is symbolic of American power and influence."
