The Quiz: Which department is headquartered at the Pentagon in Arlington, Virginia?
Dept. of Justice
Dept. of Homeland Security
Dept. of Defense
Dept. of State
While most Cabinet departments are headquartered in Washington, D.C., the DOD is located across the river in Arlington. Sprawling across 1,100 acres, the Pentagon complex was built in the early 1940s with World War II in mind. It was meant to be a temporary wartime facility due to a lack of space in D.C., but it proved useful enough to remain a permanent fixture. Today, it houses the Office of the Secretary of Defense, the Joint Chiefs of Staff, and various offices for all branches of the military.
The correct answer to this quiz is Dept. of Defense.
