The Basics

The Pentagon is a city unto itself, and its distinctive 5-sided building lays claim to six ZIP codes. Designed by American architect George Bergstrom and dedicated in 1943, the grounds are home to the 2-acre (0.80-hectare) Pentagon Memorial.

A walking tour of the Pentagon covers 1.5 miles (2.4 kilometers) over the course of an hour and highlights the missions and accomplishments of the Armed Services, the Office of the Secretary of Defense, and the Joint Staff. Many tours of Washington DC and Arlington stop at the Pentagon, whether you want to visit on a private or group tour. Hop-on, hop-off tours typically stop at the Pentagon along with DC highlights such as the White House, Jefferson Memorial, and US Capitol Building.

When to Get There

The building can sometimes be closed to visitors without notice, so it’s a good idea to check ahead of time. For scheduled tours, arrive at the security checkpoint at least an hour ahead of the tour start time. Be sure to explore the gift shop and Visitor Center, as you won’t be allowed back into these areas after your tour concludes.

The Pentagon Memorial

On September 11, 2001, terrorists hijacked American Airlines Flight 77, which crashed into the west wall of the Pentagon, penetrating three of the five rings. The area hit was under renovation at the time, and many of the offices were empty, sparing countless lives. The area has since been repaired and is now flanked by the Memorial, which is open to the public 24 hours a day. This monument to the airplane attack honors the 184 victims, symbolized by illuminated granite benches arranged in order of their ages: 3 to 71.
