If you want to visit the Pentagon Memorial Sunday to honor those who died on Sept. 11, 2001, your opportunities will be limited.
The Memorial will be closed to the public for most of the day because of formal ceremonies commemorating the 10th anniversary of the 9/11 attack and private visitations by survivors and victims' families.
The Memorial will be closed to the public Sunday until 6 p.m., as well as intermittently on Sept. 9 and 10.
The Memorial is normally open to the public.
Secretary of Defense Leon Panetta will host a remembrance ceremony Sunday morning at the Memorial to honor the memory of those killed there in the 2001 terrorist attack. This will be a private remembrance for the family members of those lost in the terrorist attack and is not open to the general public.
The Pentagon Memorial opened on Sept. 11, 2008, and is the first dedicated national commemorative to honor those killed during the 2001 terrorist attacks.
The Pentagon Memorial consists of 184 individual memorial units honoring the 59 passengers and crewmembers aboard American Airlines Flight 77 and the 125 men and women in the Pentagon who died.
