Washington's own "9/11 memorial" honors the 184 people who perished when the hijacked American Airlines Flight 77 crashed into the northwest side of the Pentagon. Benches engraved with the victims' names are arranged in order by date of birth and where they were when they died. The names of the victims who were inside the Pentagon are arranged so that visitors reading their names face the Pentagon, and names of the victims on the plane are arranged so that visitors reading their names face skyward. Designed by Julie Beckman and Keith Kaseman, the memorial opened to the public on September 11, 2008, the seventh anniversary of the attacks. Volunteer docents periodically stand near the entrance and answer questions. There is no public parking, with the exception of five stalls for handicap-permitted vehicles. Take either the blue or yellow Metro line to the Pentagon stop.
