Tower Two, New York, United States

Diamonds in the sky for NY

A diamond-shaped skyscraper, part of the new World Trade Center site, will serve as a beacon and will lead the eye down to the memorial pool from any angle in the city.
Foster's design appears to connect four narrow towers, topped by four shining diamonds that would be lit at night. It will be 1,254 feet, taller than anything in the city except for the Empire State Building. Foster's tower would have four wider floors for financial trading, a 65-foot-high lobby and retail space above and below ground.
The tower has also been placed along an axis so one side will be lit up by a ray of sunshine in the morning that on September 11 will fall at precisely 8.46am - the moment the first plane hit.
