pentagon 9

Contractors already involved with the renovation were given the added task of rebuilding the sections damaged in the attacks. This additional project was named the "Phoenix Project", and was charged with having the outermost offices of the damaged section occupied by September 11, 2002.^[43][44][45]
When the damaged section of the Pentagon was rebuilt, a small indoor memorial and chapel were included, located at the point of impact. For the fifth anniversary of the September 11, 2001 attacks, a memorial of 184 beams of light shone up from the center courtyard of the Pentagon, one light for each victim of the attack. In addition, an American flag is hung each year on the side of the Pentagon damaged in the attacks, and the side of the building is illuminated at night with blue lights. After the attacks, plans were developed for an outdoor memorial, with construction underway in 2006. The Pentagon Memorial, which consists of a park with 184 benches on 2 acres (8,100 m²) of land, according to the victims' ages, from 3 to 71, was opened to the public on September 11, 2008
