The Twin Towers are the main buildings of the World Trade Center in the financial district of New York. There are two towers of up to 110 floors, called "One World Trade Center Building" and "World Trade Center Two Building," the tallest buildings in the world at that time, exceeding The Empire State Building in Manhattan.
They were iconic buildings in New York at the time. Anyone who comes to New York can see these two towering buildings from a distance. There are many famous large companies in the two buildings, and TV station transmission towers are on the roof. These two towers are the pride of New York City and America.
Unfortunately, the Twin Towers were destroyed by the terrorist attack on September 11, 2001. The 9/11 incident not only directly caused the death of thousands of people and huge property losses but also severely hit the economic development of the United States and had a very bad impact on the world economy and security. Let's find out more facts about the Twin Towers in this post.
Description of the Twin Towers Size
The Twin Towers were the centerpieces of the World Trade Center complex, located in the World Trade Center in New York, USA, and is one of the most important masterpieces of the famous architectural artist Yamasaki. The building was built by the Port Authority of New York and New Jersey; it cost 700 million dollars and started construction in 1966. In 1972, the tallest building with a height of 417 meters was opened, surpassing the Empire State Building in New York to become the world's largest skyscraper. However, the Twin Towers collapsed in the "9 11" terrorist attack in 2001 and were already in ruins.
The 1960s to the mid-1970s was the most glorious period for the real estate industry in the United States. The twin towers of the World Trade Center Building, completed in 1973, broke the record of the world's tallest building held by the Empire State Building for 42 years and was a symbol of the prosperous period of the United States.

The project lasted seven years, and the Twin Towers of the World Trade Center became the tallest in the world with a height of 411 meters in 1973, with a total of 110 floors. The World Trade Center in New York is a complex of 7 buildings; its main building-the Twin Towers is square with a side width of about 63 meters.

There are densely placed steel columns on the periphery of the building, and the walls are composed of aluminum plates and glass windows, known as the "window of the world."

On the morning of September 11, 2001, two planes hit the Twin Towers of the World Trade Center, the fuel was dumped into the buildings, the entire building structure was destroyed in the fire, and the steel skeleton supporting the building softened. The Twin Towers became the first skyscraper in the world to collapse due to fire. Two thousand seven hundred fifty-three people were killed in the terrorist attack, which became the deadliest attack in New York's history.
The Twin Towers have long been a memory, but people will never forget the former tallest building in the world. We will always remember history and resolutely resist terrorism. The new World Trade Center Building will evoke memories of the World Trade Center Twin Towers. This young building is a single building that adopts higher safety standards. The elevators, fire extinguishing devices, and electrical pipelines are all covered and protected by a hollow concrete device with a thickness of about 6 meters. We will introduce the new World Trade Center Building in another post.
