1400 Defense Pentagon, Arlington, VA 20301
The Pentagon is located on the Potomac river in Arlington, VA, just across from Georgetown and Washington, D.C. It gets its name from the shape of the five-sided building. It is open to visitors through signing up for a Pentagon tour (see website). The Pentagon houses more than 25,000 Department of Defense employees - military, civilian, and contractors. The Secretary of Defense and the Joint Chiefs of Staff have their offices in the building. It has 5 rings, with the inner-most ring opening up into a large courtyard with a small restaurant in the middle. There is a large food court and plenty of places to eat, and many of the hallways double as a museum with exhibits including POW/MIA, Pentagon Building History, NATO, Humanitarian Assistance Missions, and more.
