This miniature architectural wire sculpture is worthy of display on the most impressive desk, cabinet, sideboard, or mantel. It is designed in America, but made in China (hence the extremely reasonable price). It is quite sturdy and solid, not flexible at all. It is part of a series of "Doodles Destinations" architectural models.
The manufacturer donates 10% of each sale of this design to the World Trade Center United Family Group Inc (WTCUFG), a nonprofit community comprised of September 11th families, survivors, and rescue workers from all over the United States and the world. WTCUFG was built on the principles of trust and shared experience and serves as a living tribute to the thousands of innocent men, women and children lost in the attacks.

The World Trade Center (WTC) was a complex in Lower Manhattan in New York City whose seven buildings were destroyed in 2001 in the September 11 terrorist attacks. The site is currently being rebuilt with six new skyscrapers and a memorial to the casualties of the attacks.
The original World Trade Center was designed by Minoru Yamasaki in the early 1960s using a tube-frame structural design for the twin 110-story towers.
Mr. Yamasaki saw the expanse as a focal point of serenity amidst the chaos of the city. Yamasaki's design included building facades sheathed in aluminum-alloy. The World Trade Center was one of the most striking American implementations of the architectural ethic of Le Corbusier and it was the seminal expression of Yamasaki's gothic modernist tendencies. The buildings were designed with narrow office windows 18 inches (45 cm) wide, which reflected Yamasaki's fear of heights as well as his desire to make building occupants feel secure.
The tube-frame design, earlier introduced by Fazlur Khan, was a new approach which allowed open floor plans rather than columns distributed throughout the interior to support building loads. The World Trade Center towers utilized high-strength, load-bearing perimeter steel columns called Vierendeel trusses that were spaced closely together to form a strong, rigid wall structure, supporting virtually all lateral loads such as wind loads, and sharing the gravity load with the core columns.
A major limiting factor in building height is the issue of elevators; the taller the building, the more elevators are needed to service the building, requiring more space-consuming elevator banks. Yamasaki and the engineers decided to use a new system with sky lobbies: floors where people could switch from a large-capacity express elevator to a local elevator that goes to each floor in a section. This allowed the local elevators to be stacked within the same elevator shaft. Located on the 44th and 78th floors of each tower, the sky lobbies enabled the elevators to be used efficiently, increasing the amount of usable space on each floor from 62 to 75 percent by reducing the number of required elevator shafts. This system was inspired by the New York City Subway system, whose lines include local stations where local trains stop, and express stations where all trains stop.
The tube frame design using steel core and perimeter columns protected with sprayed-on fire resistant material created a relatively lightweight structure that would sway more in response to the wind than traditional structures such as the Empire State Building, that have thick, heavy masonry for fireproofing of steel structural elements. One of the chief engineers, Leslie Robertson, worked with Canadian engineer Alan G. Davenport to develop viscoelastic dampers to absorb some of the sway. These viscoelastic dampers, used throughout the structures at the joints between floor trusses and perimeter columns, along with some other structural modifications, reduced the building sway to an acceptable level.
1 World Trade Center, also known by its nickname and former name, Freedom Tower, will be the main building of the new World Trade Center, now under construction in Lower Manhattan in New York City. The tower will be located in the northwest corner of the 16-acre World Trade Center site. Three other high-rise office buildings are planned for the site, and they will surround the World Trade Center Memorial, which is under construction. The area will also be home to a museum. When completed, 1 World Trade Center will be the tallest building in the United States as well as one of the tallest in the world. It will also stand as the tallest all-office building in the world.
