What Is the Pentagon?

The Pentagon is the headquarters of the United States Department of Defense. It sits in Arlington County, Virginia, across the Potomac River from Washington, D.C.

People often say "The Pentagon" to mean the leaders of the department. This is because the building stands for the U.S. military.

Where Is It?

The Pentagon is near Arlington National Cemetery, Pentagon City, and Crystal City. Its west side faces Washington Boulevard.

The Pentagon is the world's third-largest office building. It has five sides and five floors above the ground. Many people work inside, and there are places to eat, exercise, and pray.

How It Was Built

The building was designed by American architect George Bergstrom. It was built by a company led by John McShain. Work began in 1941, during a difficult time when countries did not get along.

The building opened on 15 January 1943. Steel was hard to get, so most of it was made of strong concrete.

A Place to Remember

A very sad event happened at the Pentagon in 2001. In 2008, an outdoor memorial opened near the building. It helps people remember those who were there.

The Hall of Heroes inside the building honors people who received the Medal of Honor. This is the highest award the U.S. military gives.
