Pentagon

The headquarters of the United States Department of Defense are housed in the massive Pentagon, whose five wedge-shaped sections represent the five branches of the U.S. Armed Forces.

On September 11, 2001, terrorists hijacked American Airlines Flight 77 and crashed it into the northwest side of the Pentagon, killing 125 people working at the Pentagon and 59 people aboard the plane. The Pentagon has since been completely restored and tours are once again available, in accordance with certain procedures .
