One World Trade Center

One World Trade Center, the skyscraper that rose from the rubble of the September 11, 2001 terror attacks. Over the course of nine years, more than 25,000 workers helped raise the steel, concrete and glass to construct the 1,776-foot-tall tower, the highest in the Western Hemisphere.

Designs

Though it was not officially a design competition, the Innovative Design Study for the then-named Freedom Tower was perceived by the public as one.

Designs

Dozens of paper models created in the search for the right shape for the new building to replace the Twin Towers.

David Childs, of Skidmore, Owings and Merrill (the architecture firm that built some of the tallest towers on Earth), changed the tower’s shape while keeping its planned height of 1,776 feet (a nod to America’s Independence Day).

Slurry Walls

In the past everything west of Greenwich Street in Manhattan was under water. The original Twin Towers were fortified by slurry walls - watertight support structures to prevent water from entering the tower’s foundations.

During work on ground zero, the slurry walls were fortified with additional concrete, and supported by auxiliary walls to resist additional lateral hydrostatic pressure, from water and soil.

The Last Column

The “last column” - a 36-foot-tall column salvaged from the South Tower - resides in Foundation Hall. The column - covered in graffiti and inscriptions by recover workers, photos and mementos - was the last removed from the debris of ground zero.
