All of these structures were constructed between 1975 and 1985 for $400 million (equal to $2,600,000,000 in 2020 money). The complex included 13,400,000 square feet (1,240,000 m 2) of office space and was located in New York City's Financial District. It was the world's largest office building at the time it was completed.
The World Trade Center was a collection of three interconnected buildings: World Trade Center Tower 1, World Trade Center Tower 2, and World Trade Center Tower 3. Construction on the first two towers began in 1973 and they were completed in 1974 and 1976, respectively. Tower 3 started construction in 1982 and was not finished until after 9/11 because of damage caused by the September 11 attacks. All three towers were 747-foot (233 m) tall when completed in 1985. The World Trade Center complex was owned by a private company that leased space to businesses.
What is so special about this building? This supertall skyscraper held the record for the tallest free-standing structure in the world for 10 years after its completion in 1985. It also became the symbol of New York City's economic power and prestige and has been referred to as the "Tower of Manhattan."
Why do we need taller buildings? There are two reasons why we need taller buildings: more space and better views.
The Marriott World Trade Center (3 WTC), 4 WTC, 5 WTC, 6 WTC, and 7 WTC were among the other buildings in the complex. The office area in the facility was 13,400,000 square feet (1,240,000 m2). The primary complex cost $400 million to build between 1966 and 1975 (equivalent to $2.27 billion in 2021).
3 WTC was the first building to be completed at the site, in November 1973. At 1,598 feet (500 m) tall, it was the tallest building in New York until the 2 WTC was completed in 1972. The Marriott World Trade Center held 240 rooms and was designed by Cesar Pelli with architectural firm Thom Mayne & Associates. It was located on the 100th floor of 3 WTC.
4 WTC was built next and opened in July 1974. It was also designed by Cesar Pelli and is similar in design to 3 WTC. It reached a height of 1,451 feet (443 m) and contained 200 rooms. It too was located on the 100th floor of 4 WTC.
5 WTC was the last of the original World Trade Center buildings to be completed in September 1975. At 1,453 feet (442 m) it was taller than both of its neighbors and held 220 rooms. It too was located on the 100th floor of 5 WTC.
6 WTC was built after 9/11 to replace those that had been destroyed.
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. They were the highest buildings in New York City, and for a short time after they were finished, they were the tallest structures in the world.
When they were built in 1973 and 1974, 1 World Trade Center was the first skyscraper to reach 100 stories and be over 1,000 feet tall. At the time it was completed, it was also the most expensive building ever erected. 2 World Trade Center followed not long afterward and was also considered a masterpiece of modern architecture. It was built by the same company as 1 World Trade Center but at a cost of only $140 million instead of $150 million.
What is so special about these two towers? Well, they are unique in that they use steel frames with concrete shells. The Trade Centers were designed by Skidmore, Owings & Merrill LLP, who also designed the Sydney Opera House. The firm wanted to create a structure that was simple yet elegant, functional yet inspiring. They succeeded!
You may have seen photos or videos of people jumping from the tops of the Trade Centers before they were demolished. That happened because each floor has an emergency door that can be opened from the inside to allow people to escape. These doors were closed before the attacks so no one would panic and jump.
The skyscraper's position provides spectacular views of the adjacent Panama Bay and the Pacific Ocean. The skyscraper's construction began in 2007 and was completed in 2011, at a cost of $400 million. It is currently the second-highest building in Panama City and the tallest outside of New York or Chicago.
Panama City is a city on the Caribbean coast of Panama. With an estimated population of 447,000, it is the most populous city in Panama and the Panamanian capital city. It is also the largest metropolitan area in Panama. Located on the Gulf of Mexico about 50 miles from Colombia, Panama City has been described as a "mini-Miami".
The city was founded in 1519 by Spanish colonists who named it after Francisco de Panama, a military officer they had hired to help them fight against the indigenous Tumbes Indians. It later became a free town and then a fortress before finally being made into a city. During its early years, it grew rapidly due to its strategic location between Europe and America. In 1785, after the French invaded Panama, they left behind many settlers who established small farms around the city. By 1821, most of these farmers had moved away from what was now called "City Gardens" because they were no longer able to grow crops there due to the heat.
