The Pentagon 9/11 Memorial park consists of 184 memorial units for each of the lives lost when Flight 77 crashed into the Pentagon on September 11, 2001.   The memorial units representing the 59 lives lost on Flight 77 face so that when reading the name of the victim to whom that unit is dedicated, the visitor to the memorial park faces the sky. When looking at a memorial unit dedicated to one of the 125 victims who were working inside the Pentagon, the visitor will see the victim’s name and the Pentagon in the same view.  It is open seven days a week 24 hours a day.
