World Trade Center

World Trade Center
The World Trade Center in New York City, United States, (sometimes informally referred to as the WTC or the Twin Towers) was a complex of seven buildings in Lower Manhattan, mostly designed by architect Minoru

Yamasaki and engineer Leslie Robertson and developed by the Port Authority of New York and New Jersey. It was initiated in 1960 by a Lower Manhattan Association created and chaired by David Rockefeller, who had the original idea of building the center, with strong backing from the then-New York governor, his brother Nelson Rockefeller.

The World Trade Center, New York, like most World Trade Centers located around the globe, belonged to the family of World Trade Centers Association. Prior to its destruction, Larry Silverstein held the most recent lease to the complex, the Port Authority having leased it to him in July 2001. The complex, located in the heart of New York City's downtown financial district, contained 13.4 million square feet (1.24 million m?) of office space, almost four percent of Manhattan's entire office inventory at that time.

Best known for its iconic 110-story twin towers (101 usable floors, eight engineering-only "service" floors on top of a lobby which was three stories high) the World Trade Center was beset by a fire on February 13, 1975 and a bombing on February 26, 1993.

All seven original buildings in the complex were destroyed by terrorists linked to Al-Qaeda on September 11, 2001. Three of the buildings collapsed: One World Trade Center (1 WTC, the North Tower), Two World Trade Center (2 WTC, the South Tower), and 7 World Trade Center (7 WTC). The Marriott World Trade Center (3 WTC) was crushed by the collapses of 1 WTC and 2 WTC. 4 World Trade Center (4 WTC), 5 World Trade Center (5 WTC), and 6 World Trade Center (6 WTC) were damaged beyond repair and later demolished. Three buildings not part of the complex were also destroyed: St. Nicholas Greek Orthodox Church was destroyed by the collapse of 2 WTC. The Deutsche Bank Building and Borough of Manhattan Community College's Fiterman Hall were damaged beyond repair by the collapse of 7 WTC; these are currently being deconstructed.
The Lower Manhattan Development Corporation, the agency charged with coordinating the reconstruction of the World Trade Center site, selected themaster plan, Memory Foundations by Daniel Libeskind, which includes the 1,776 ft (541 m) Freedom Tower. The height of 1,776 feet (541 m) was chosen as a reference to the year of American independence. A new 7 World Trade Center office building, which was not part of the site master plan, officially opened on May 23, 2006.
The Lower Manhattan Development Corporation sponsored the World Trade Center Site Memorial Competition, an international design competition for the World Trade Center Memorial in spring 2003. The winning design, Michael Arad and Peter Walker's Reflecting Absence, was chosen in January 2004.

The World Trade Center name will continue to be used as name of the site, as will the New York City Subway and PATH train stations that serve the complex. A temporary PATH station, largely following the layout of the original, is the first part of the complex to have reopened.

On November 22, 2004, New York Governor George Pataki named the living former presidents as honorary members of the board rebuilding the World Trade Center.

On May 18, 2005, Donald Trump, long-time opponent of the Freedom Tower, proposed the Twin Towers II plan to rebuild the Twin Towers with various safety, structural, and technological improvements.

On June 29, 2005, a redesigned Freedom Tower was unveiled which more closely resembled the character of the fallen towers. The new design also boasted several safety improvements over previous proposals.

On December 15, 2005, Sir Norman Foster was announced as the architect who will design the second of five new office towers planned for the site.

On March 13, 2006 workers arrived at the World Trade Center site to remove remaining debris and start surveying work. This marks the official start of construction of the WTC Memorial and Museum.

In April 2006, a tentative agreement was reached by the owner of the site, The Port Authority, and private developer Larry Silverstein. The main elements of that agreement are that Silverstein ceded rights to develop the Freedom Tower and Tower Five in exchange for financing with Liberty Bonds for Tower Two, Three, and Four which are considered to be the most marketable properties of the site. On April 27, 2006, a ground breaking ceremony was held for the Freedom Tower.

In May 2006, architects Richard Rogers and Fumihiko Maki were announced as the architects for Towers Three and Four, respectively.

The final designs for Towers Two, Three and Four were unveiled on September 7, 2006. Tower Two, or 200 Greenwich Street, will have a roof height of 1,254 feet (382 m) and a 96-foot (29 m) tripod spire for a total of 1,350 feet (411 m). Tower Three, or 175 Greenwich Street will have a roof height of 1,155 feet (352 m) and an antennae height of 1,255 feet (383 m). Tower Four, or 150 Greenwich Street, will have an overall height of 946 feet (288 m).

As of late 2007, work at the World Trade Center site continued. Foundation work has started on the Freedom Tower, Calatrava Hub, and the memorials.

On June 22, 2007 the Port Authority of New York and New Jersey announced that JP Morgan Chase will build Tower 5, a 42 story building on Site 5 currently occupied by the Deutsche Bank Building. Kohn Pedersen Fox was officially chosen as the architect for the building on July 17, 2007.
