Pentagon Memorial, Washington D.C.

The Victims of the Terrorist Attack on the Pentagon Memorial serves as a tribute to the 184 individuals who lost their lives on American Airlines Flight 77 and within the Pentagon building on September 11, 2001, when it was targeted by al-Qaeda terrorists.

This memorial site is located at Arlington National Cemetery and includes a 4.5-foot (1.4-meter) tall granite marker in the shape of a pentagon. On the upper part of this marker, the words "Victims of Terrorist Attack on the Pentagon September 11, 2001" are engraved. Five aluminum plaques, painted black, bear the names of the 184 victims of the terrorist attack. Each plaque corresponds to one side of the marker. Notably, the names of those who were on Flight 77 are marked with a diamond symbol in front of their name, while individuals for whom no remains could be identified are indicated with a star symbol in front of their name. The memorial also features a pentagonal base extending approximately 5 inches (13 cm) outward and downward from the main body of the monument.

The memorial site occupies an area of 1.93 acres (0.78 hectares) and was designed by John C. Metzler, Jr., the Superintendent of Arlington National Cemetery. It was commissioned by the United States Department of Veterans Affairs on September 12, 2002.
