What happened on 9/11?
The September 11th attacks, also known as 9/11, were a series of coordinated terrorist attacks that occurred in the United States on September 11, 2001. The attacks were carried out by 19 terrorists affiliated with the Islamic extremist group al-Qaeda, who hijacked four commercial airplanes with the intention of crashing them into significant targets.
- Two of the planes were flown into the Twin Towers of the World Trade Center in New York City, causing the collapse of both towers and resulting in the deaths of nearly 3,000 people, including civilians, first responders, and airline passengers and crew.
- Another plane was flown into the Pentagon in Arlington, Virginia, killing 125 people inside the building and all 64 people on the plane.
- The fourth plane, United Airlines Flight 93, was headed for Washington, D.C., but crashed in a field near Shanksville, Pennsylvania, after passengers attempted to overcome the hijackers.
The 9/11 attacks were the deadliest terrorist attack in world history and resulted in significant changes in security and policy around the world. The attacks also led to the United States launching the War on Terror, which resulted in military operations in Afghanistan, Iraq, and other countries. The legacy of 9/11 continues to be felt today, both in the ongoing efforts to combat terrorism and in the memorialization of the victims and the events of that day.
9/11 Memorial Pools / Ground Zero
9/11 Memorial Pools, also known as the National September 11 Memorial, are two large reflecting pools located in the exact footprints of the Twin Towers of the World Trade Center in Lower Manhattan, New York City. Each pool is nearly an acre in size and features the largest man-made waterfalls in North America.

How many names are on the 9/11 Memorial?
The pools are surrounded by bronze panels that are inscribed with the names of the nearly 3,000 people who lost their lives in the terrorist attacks on September 11, 2001, as well as the six people who were killed in the bombing of the World Trade Center in 1993.


The names are arranged according to where individuals were at the time of the attacks, and special symbols indicate firefighters, police officers, and other first responders who lost their lives.
Design of the pools
The design of the 9/11 Memorial Pools is a significant aspect of the overall memorial. The pools were designed by architect Michael Arad and landscape architect Peter Walker, and their design was selected from a competition that attracted more than 5,000 entries from 63 countries.
The pools are each nearly an acre in size and are located in the exact footprints of the Twin Towers. The pools are lined with a special synthetic granite and feature the largest man-made waterfalls in North America, which cascade down into the pools. The waterfalls help to drown out the noise of the city and create a tranquil atmosphere for visitors to reflect and pay tribute to those who lost their lives.
Why is it called Ground Zero?
The term Ground Zero was originally used to describe the point on the earth’s surface directly below the location of a nuclear explosion. The term was first used in this context during the Manhattan Project, the US government’s research and development program to create the first atomic bomb during World War II.
Following the 9/11 attacks on the World Trade Center, the term Ground Zero was used to describe the site of the attacks in New York City. The term became widely used in the media and in popular culture to refer to the location where the Twin Towers once stood.
The use of the term Ground Zero to describe the site of the 9/11 attacks has been criticized by some as being insensitive or inappropriate, as it is associated with the destruction and devastation of a nuclear explosion.
However, the term has remained in use and is now widely recognized as a term that refers specifically to the site of the attacks on September 11, 2001.
National September 11th Memorial Museum
The museum is dedicated to preserving the memory of the September 11, 2001 terrorist attacks. The museum features various exhibits, artifacts and personal stories of survivors, first responders and family members of victims. You can see the highlights of the museum below.
- Twin Tower Tridents: The Twin Tower Tridents are two large steel structures that were part of the original design of the Twin Towers. The tridents were located at the base of the buildings and supported the weight of the towers. After the collapse of the towers on 9/11, the tridents were recovered from the rubble and became symbols of resilience and strength in the aftermath of the attacks. The tridents are now on display in the museum, providing visitors with a tangible connection to the iconic buildings that once stood on the site.


- Slurry Wall: The Slurry Wall is a massive concrete structure that served as a foundation for the original World Trade Center complex. The wall was built to prevent the Hudson River from flooding the site, and its strength and stability helped to prevent further damage to the surrounding area during the collapse of the towers on 9/11. The Slurry Wall is now an integral part of the National September 11th Memorial, as it forms part of the foundation of the Memorial Pools. The Slurry Wall is also on display in the museum, providing visitors with a powerful reminder of the engineering and construction feats that made the original World Trade Center possible.
- Last Column: The Last Column is a steel column that stood at the heart of the World Trade Center site, serving as a symbol of hope and resilience during the recovery effort. Covered in messages of support, gratitude, and remembrance from rescue workers, the column was the final piece of steel to be removed from the site in May 2002. It now stands in the museum as a tribute to the thousands of individuals who worked tirelessly in the aftermath of the attacks.
- Survivors’ Staircase: The Survivors’ Staircase is a staircase that was originally located in the World Trade Center complex and provided an escape route for hundreds of people on 9/11. The staircase survived the collapse of the towers and was relocated to the museum as a testament to the bravery and determination of those who survived the attacks.
- Ladder Company 3: Ladder Company 3 was one of the first emergency responders on the scene of the September 11 attacks in New York City. The company’s truck, which was badly damaged during the attacks, has since become an iconic symbol of the courage and sacrifice of the first responders who risked their lives to save others that day.

- Elevator Motor: The Elevator Motor is an artifact that was recovered from the wreckage of the World Trade Center. The motor was part of the elevator system that served the Twin Towers, and was located in the North Tower. The motor was discovered during the recovery effort and is now on display in the museum. The artifact serves as a reminder of the massive scale of the World Trade Center complex, and the crucial role that elevators played in transporting workers and visitors to the upper floors.
