The World Trade Center in New York City (sometimes informally referred to as the WTC or the Twin Towers) was a complex of seven buildings in Lower Manhattan, mostly designed by American architect Minoru Yamasaki and engineer Leslie Robertson and developed by the Port Authority of New York and New Jersey.
The towers were designed in the plain, box-like International architectural style, which at the time of their construction was just gaining popularity as ther mosdt popular style in inner city architecture of the Baby Boomer years; the towers helped popularise the style and inspired similar glass-walled office towers in cities across the world, including Australia's capital cities.
The Center 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 all World Trade Centers located around the globe, belonged to the family of World Trade Centers Association. 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 m2) of office space, almost four percent of Manhattan's entire office inventory at that time. Best known for its iconic 110-story twin towers, the World Trade Center was beset by a fire on 13th February 1975 and a bombing on 26th February 1993. Despite the first two disasters, the World Trade Center was a part of New York City's identity and was recognized all over the world as an icon both for the United States of America and for the free world as the West was known.
