The towers measured 208 feet long by 208 feet wide. Although only Tower 1 had an antenna, the construction of each building was built to support a broadcast mast, and until September 11th, 2001, The Mall at the World Trade Center was Manhattan's biggest mall. It contained more than 160 stores and restaurants.
The twin towers were the highest buildings in New York City when they were completed in 1973. At 1,453 feet, they were also the tallest buildings in the world for three years after their completion. They stood for over 100 years before the Chrysler Building was finished in 1929. The Woolworth Building followed in 1933 and it is now considered one of the first skyscrapers.
There are several reasons why the Twin Towers were so popular with architects: they're huge, they're cheap to build, there's plenty of space inside them, and they have great views. The main problem was that they were made of steel and concrete which are very heavy. The weight of the buildings was supposed to be distributed through large foundations but in fact they had small ones which made the buildings prone to collapse in an earthquake.
On September 11th, 2001, two airplanes crashed into the Twin Towers killing 2,711 people. The buildings then collapsed during the next hour and half because they were not constructed properly. All that remained was a pile of rubble from where the towers used to stand.
It opened on April 4, 1973, and was destroyed after the September 11, 2001, attacks. The original 1 World Trade Center (the North Tower), at 1,368 feet (417 m), and 2 World Trade Center (the South Tower), at 1,362 feet (415.1 m), were the highest structures in the world at the time of their construction. They were surpassed by the 1,453-foot (442 m) Sears Tower in Chicago when it was completed in 1983.
The two towers were initially planned as separate buildings, but development costs prevented their completion. So they were joined together at their cores, creating a single tower with four equal sections - each section is about 42 stories high - connected by three skywalks.
In 2010, a new United States Supreme Court building was completed across from the old One World Trade Center. The 110-story skyscraper is now the tallest building in New York City and the third tallest in the United States. It stands 514 feet (157 m) taller than its predecessor.
Also in New York City, another skyscraper is under construction. When it is complete in 2014, the 2,716-foot (828 m) MetLife Building will be the second-highest office building in America behind the 2,722-foot (831 m) Willis Tower (formerly known as the John Hancock Center).
110 tales The World Trade Center complex was centered on the Twin Towers. 1 WTC (North Tower) and 2 WTC (South Tower) both had 110 floors and supplied almost 10 million square feet of office space for about 35,000 workers and 430 businesses.
The Twin Towers were the tallest buildings in New York until 2001 when World Trade Center towers were completed. They were built by the Silverstein family and were located at One World Trade Center and Two World Trade Center. The two towers were identical except for their heights: 1,776 feet for the North Tower; 2,443 feet for the South Tower.
The Twin Towers were destroyed on September 11, 2001 when al-Qaeda terrorists hijacked several commercial airplanes and used them as weapons to kill over 3000 people in the United States.
After 9/11, Congress passed a law requiring the construction of high-rise buildings in major cities across America. The law was called the Biggert-Waters Act after its sponsors, Senator James E. Watson (D-MN) and Representative Bob Waters (D-NY). It was intended to reduce crime by preventing people from hiding in upper floors of tall buildings to shoot police officers or commit other crimes. The law required that new office buildings be constructed with security features such as metal detectors at the entrance of each floor and surveillance cameras on every floor.
The North Tower The original 1 World Trade Center (the North Tower), at 1,368 feet (417 m), and 2 World Trade Center (the South Tower), at 1,362 feet (415.1 m), were the highest structures in the world at the time of their construction. 1973–2001: World Trade Center.

The tower is 1,368 feet tall from the ground to the metal and glass balustrade on top, matching the height of the Twin Towers. One World Observatory is the name of the observation deck at One World Trade Center. The viewing platform there offers a 360-degree view that includes downtown Manhattan, Brooklyn, New Jersey, and Connecticut.
The Freedom Tower will be 1,776 feet tall, making it the tallest building in New York City. The redesign also added a new third floor with more than 100,000 square feet of office space. The original plan was to name the top two floors "Observatory" and "Research," but during development discussions it was decided that this would be confusing since both names could apply to any one of several other skyscrapers around the world. So the top two floors were named simply "Freedom" and "Liberty."
The building is being constructed by the Chicago-based developer Tishman Speyer, which also built the Twin Towers. The company said that designing and engineering the new tower was a challenge because it had to be as strong as, if not stronger than, the old one while using much less material. The new Freedom Tower should be completed in 2014 and will be ready for guests to check in and out of their offices. By then, the former site of the Twin Towers will have been rebuilt in a different location within the city limits.
