NEW YORK CITY, USA New building at WTC site could be world's tallest
The winning plan for rebuilding the World Trade Center site was designed by architect Daniel Libeskind, who proposed a 1,776-foot-tall tower, symbolizing the year of American independence. The top floors will be filled with life-affirming indoor gardens. The plan will leave large portions of the 70-foot-deep Ground Zero pit open, exposing the concrete foundation walls that survived the towers' collapse.
