11 Fascinating Facts About The Twin Towers

The construction cost of the Twin Towers was $900 million, which would be over $5 billion today when adjusted for inflation.

The story of the Twin Towers has captured the attention of many people for decades, from their beginnings as the tallest buildings in the world to their tragic destruction during the 9/11 attacks.

The Twin Towers were two of the seven buildings that made up the original World Trade Center in Lower Manhattan, New York, and were named the North Tower and the South Tower.

They Were Once the Tallest Buildings in the World

When the Twin Towers were first completed, they were the tallest buildings in the world, standing at 1,368 ft and 1,362 ft respectively. They were both taller than their neighbor, the Empire State Building, and the Eiffel Tower in Paris, France.

They Were Completed in 1973

The construction of the North Tower began in 1968, followed by the South Tower in 1969. The buildings were finished by 1973, along with four of the other World Trade Center buildings. The seventh and final building, 7 World Trade Center, was finished by 1987.

Their Names Were Not Very Creative

Like many buildings, there was not much creativity involved in the names of the Twin Towers. They were officially named 1 World Trade Center and 2 World Trade Center, also known as the North Tower and South Tower respectively.

They Were Almost Identical

Although not identical, the Twin Towers were very similar in appearance. The North Tower was taller than the South Tower by just 6 ft, but this was hardly noticeable from the ground.

They Survived Robberies, Fires, and Bombs

The Twin Towers survived many disasters throughout their existence. In 1993, a bomb was detonated in the World Trade Center parking lot, injuring more than a thousand people and killing six. In 1975, a fire broke out in the North Tower and spread across six floors.

Philippe Petit Walked Between the Towers

Philippe Petit, a French daredevil, became famous for his high-wire walk between the Notre Dame Cathedral towers in Paris in 1971. Three years later, he performed another high-wire walk between the Twin Towers, which was even higher, at more than 1,312 ft.

They Were Part of the World Trade Center

The Twin Towers were two of the seven buildings that made up the original World Trade Center complex in Lower Manhattan, New York. The other five buildings were known as 3-7 World Trade Center.

The 11th floor sustained most of the damage from the fire that broke out.

In 1998, the Port Authority of New York and New Jersey decided to privatize the entire World Trade Centre, which included the Twin Towers, following a robbery of $1.6 million USD in cash from the Bank of America located within the North Tower.

A daredevil stunt was performed by George Willig in 1977, where he scaled the outside of the South Tower all the way to the top in under four hours, earning him the name “the human fly”.

The Twin Towers were built using a tube design, created by Fazlur Rahman Khan, which allows for an open-plan floor and a flexible design.

The construction of the towers cost $900 million USD, surpassing initial estimates, and not everyone was happy with the project, as a group of builders formed the “Committee for a Reasonable World Trade Center” criticizing the size and scale of the new buildings.

The top floor of the North Tower was controlled by the South Tower, and the operations control center was located in the basement of the latter.

Finally, the North Tower was home to radio and TV transmission in New York.

The Empire State Building and the Alpine Tower were the only two options left after the collapse of the Twin Towers, and the Alpine Tower was eventually chosen. The North Tower of the Twin Towers had a popular restaurant called “Windows of the World” on the 106th and 107th floors. The Port Authority established this restaurant to make the towers more attractive to tourists. With stunning views of the Manhattan skyline, the restaurant opened in April 1976. In 1993, the restaurant was damaged during the first bombing, but it was restored after a $25 million USD investment. While the Twin Towers were never rebuilt, they remain famous and have been featured in many documentaries, dramas, and TV shows. Their story and tragic ending ensure their place in history for years to come.
