The National September 11 Memorial commemorates the lives lost, recognizes those who survived and allows a place for visitors to come together in the spirit of unity.
Opened on the 10th anniversary of the attacks, the 9/11 Memorial consists of two pools set in the footprints of the original twin towers. Thirty foot waterfalls cascade from the four walls of each pool into the pools' centers. The names of the victims are inscribed in bronze along the parameter of the pools.
Construction continues to this day on the redeveloped 1 World Trade Center which is located just beyond the north pool. This building will be the tallest in the U.S. standing 1,776 feet. Its top spiral was installed last month.
Just east of the south pool, 4 World Trade Center will rise 72 floors and stand 977 feet tall.
