The new World Trade Center (WTC) is a group of buildings in Lower Manhattan, New York City. It replaced the original seven buildings that were destroyed during the September 11 attacks in 2001. This area is now home to several skyscrapers, a memorial and museum, a park, a church, a performing arts center, and a transportation hub.
The main building of the new complex is the 104-story One World Trade Center. It is the tallest building in the Western Hemisphere. The original World Trade Center, including the famous Twin Towers, opened in 1973. They were the tallest buildings in the world at that time.
On September 11, 2001, terrible attacks caused the Twin Towers to collapse. This event killed 2,753 people. The cleanup and recovery at the site took eight months. After that, plans began for rebuilding.
After some delays, construction started in 2004. The new complex includes One World Trade Center, 3 World Trade Center, 4 World Trade Center, and 7 World Trade Center. Another tall office building is planned at 2 World Trade Center. The site also has a museum, a memorial, and a large transportation hub.
7 World Trade Center was the first skyscraper to open in the new complex on May 23, 2006. 4 World Trade Center opened on November 12, 2013. The National September 11 Memorial opened on September 11, 2011, and the Museum opened on May 21, 2014. One World Trade Center opened on November 3, 2014. The Transportation Hub opened on March 4, 2016, and 3 World Trade Center opened on June 11, 2018.

The Original World Trade Center and 9/11
The first World Trade Center had the famous Twin Towers. These were 1 WTC and 2 WTC. They became the tallest buildings in the world when they opened in 1973. Other buildings in the complex included the Marriott World Trade Center (3 WTC), 4 WTC, 5 WTC, 6 WTC, and 7 WTC.
On September 11, 2001, hijackers crashed two planes into the Twin Towers. The first plane hit the North Tower at 8:46 a.m. The second plane hit the South Tower at 9:03 a.m. The South Tower collapsed at 9:59 a.m., and the North Tower fell at 10:28 a.m. These attacks killed 2,753 people. The collapse also damaged many nearby buildings, destroying the entire complex.
The cleanup and recovery at the site lasted for eight months. Debris was taken to Fresh Kills Landfill on Staten Island. A ceremony on May 30, 2002, marked the end of the cleanup.
In 2002, construction began on a new 7 World Trade Center. This building was just north of the main site. It was rebuilt quickly because it was not part of the main rebuilding plan. The new 7 WTC was designed to allow Greenwich Street to pass through the complex again. A temporary train station opened in 2003. It was replaced by a permanent station in 2016.
Planning the New World Trade Center
After the attacks, many people shared ideas for rebuilding the site. Some wanted only a memorial. Others wanted to rebuild new office buildings. The Governor of New York, George Pataki, wanted to find a balance.
In 2001, the Lower Manhattan Development Corporation (LMDC) was created. This group was in charge of overseeing the rebuilding. They worked with different groups, including victims' families and local businesses.
In 2002, the LMDC asked architects for new designs. Six initial designs were not popular. So, a new international design competition was announced. Seven teams of architects were chosen to compete.
In February 2003, two finalists were chosen: the THINK Team and Studio Daniel Libeskind. After some discussion, Studio Daniel Libeskind won the competition. His plan was called "Memory Foundations."
Libeskind's plan was changed a lot over time. It included the One World Trade Center, a memorial, and other office towers. The design for the memorial, called Reflecting Absence, was chosen in January 2004. It was designed by Michael Arad and Peter Walker.
A key idea from Libeskind's plan was to turn the original Twin Towers' footprints into a memorial. They would not be used for new buildings. This idea was very important to many people.
Debates and Challenges
There were many debates about what to build at the site. Some people wanted the World Trade Center to look exactly as it did before 9/11. Others wanted the entire site to be a memorial. Finally, a plan was agreed upon. It included a memorial and museum where the Twin Towers stood. Six new skyscrapers would surround it.
The original North Tower had a famous restaurant called "Windows on the World." Many people wanted this landmark to be rebuilt. However, the Port Authority decided not to rebuild it. This decision upset some people.
Building the new World Trade Center took a long time and cost a lot of money. In 2010, a TV show reported on the slow progress. The main tower, One World Trade Center, had three different designs. The project faced many delays and high costs.
One World Trade Center also received some criticism. Its first design was changed because people did not like it. The final design had a strong, windowless base. Some thought it looked dull. Designers added special glass panels to make it look better. The name was also changed from "Freedom Tower" to "One World Trade Center."
Rebuilding Progress
Early Steps and Final Plans
The final design for the World Trade Center was ready in 2005. But security concerns caused delays. New plans for the Transportation Hub also pushed back the timeline. The memorial was very important to victims' families. So, it was decided to build the memorial first, even if it meant delaying the transportation hub.

In 2006, the Port Authority took over ownership of One World Trade Center. On March 13, 2006, workers began clearing debris and surveying the site. This marked the official start of the memorial's construction. On April 27, 2006, a groundbreaking ceremony was held for the Freedom Tower. It was designed to be 1,368 feet tall, like the original North Tower. Its spire reaches a symbolic height of 1,776 feet, honoring the year the United States Declaration of Independence was signed.
In May 2006, architects were chosen for 3 World Trade Center and 4 World Trade Center. The new 7 World Trade Center opened on May 23, 2006. It was the first tower in the complex to reopen.
In 2007, JPMorgan Chase planned to build 5 World Trade Center. However, their plans changed, and construction stopped.
Work continued on One World Trade Center. It reached ground level by 2010. Then, it grew by one floor each week. Publisher Condé Nast agreed to move its headquarters there in 2010. This helped attract other businesses.
The St. Nicholas Greek Orthodox Church was destroyed in the attacks. After some disagreements, a deal was made in 2011 to rebuild the church.
Major Milestones
By August 2011, One World Trade Center was 80 stories tall. 4 World Trade Center was about 38 stories high. The National September 11 Memorial opened to families on September 11, 2011.

Shopping and Retail Space
The Westfield World Trade Center mall opened on August 16, 2016. It has a large amount of retail space. This makes it the biggest shopping mall in Manhattan again. The mall has two levels underground. There are also three levels above ground in the lower parts of 2 World Trade Center and 3 World Trade Center. 4 World Trade Center has four levels of shops. The main building of the Transportation Hub, called the Oculus, also has many stores.
The Transportation Hub
The World Trade Center Transportation Hub was designed by Santiago Calatrava. It replaced the old train station. This hub connects the PATH train station to several subway lines. It also links to the Battery Park City Ferry Terminal and other buildings. The hub formally opened on March 3, 2016.
The Performing Arts Center
The Perelman Performing Arts Center was announced in 2004. It was renamed in 2016 after Ronald Perelman donated money. A new design was revealed in September 2016. Construction began in 2017, and the center opened on September 13, 2023.

The World Trade Center Logo
The new World Trade Center logo was revealed in August 2014. It was designed by Landor Associates. The logo is shaped like a "W" and has many meanings:
- The five bars represent the five main towers of the complex.
- The top bars are cut at a 17.76-degree angle. This reminds us of One World Trade Center's 1,776-foot height.
- Two white columns at the top symbolize the Tribute in Light memorial.
- Three black bars at the top represent the original Twin Towers' trident-shaped columns.
- Two black bars at the bottom stand for the twin pools of the National September 11 Memorial & Museum.
- The whole logo looks like a "W" for "World Trade Center" and "Westfield World Trade Center".
