But unlike the memorial, the Freedom Tower is not intended to evoke memories of the past; it rises upward, bright and shining, representing optimism and a vision of the future.
The 541.4 metre building will be built to plans by Daniel Libeskind and David Childs, though the New York Police Department has demanded a series of changes to the project for security reasons. The foundation plate (a 200 foot or 60.96 metre square) will be shifted 90 feet (27.4 metres) from West Street, because the biggest worry is the building¿s vulnerability to another attack, this time from the ground by a car bomb most likely to come from West Street.
The building will be reinforced with a concrete wall covered with steel and titanium.
The base of the tower will therefore no longer be shaped like a parallelogram, but like a cube; it will change shape as it rises upward, transforming the square base into eight isosceles triangles so as to form a perfect flat octagon halfway up. At the end of the tower, a 276 foot spire lit up by night will rise upward to recall the torch of the Statue of Liberty.
