World Trade Center site in the context of "7 World Trade Center"

One World Trade Center, also known as One WTC and as the Freedom Tower, is the main building of the rebuilt World Trade Center complex in Lower Manhattan, New York City. Designed by David Childs of Skidmore, Owings & Merrill, One World Trade Center is the tallest building in the United States, the tallest building in the Western Hemisphere, and the seventh-tallest in the world. The supertall structure has the same name as the North Tower of the original World Trade Center, which was destroyed in the terrorist attacks of September 11, 2001. The new skyscraper stands on the northwest corner of the 16-acre (6.5 ha) World Trade Center site, on the site of the original 6 World Trade Center. It is bounded by West Street to the west, Vesey Street to the north, Fulton Street to the south, and Washington Street to the east.

The construction of below-ground utility relocations, footings, and foundations for the new building began on April 27, 2006. One World Trade Center became the tallest structure in New York City on April 30, 2012, when it surpassed the height of the Empire State Building. The tower's steel structure was topped out on August 30, 2012. On May 10, 2013, the final component of the skyscraper's spire was installed, making the building, including its spire, reach a total height of 1,776 feet (541 m). Its height in feet is a deliberate reference to the year when the United States Declaration of Independence was signed. The building opened on November 3, 2014; the One World Observatory opened on May 29, 2015.

The Tribute in Light is an art installation created in remembrance of the September 11 attacks. It consists of 88 vertical searchlights arranged in two columns of light to represent the Twin Towers. It stands six blocks south of the World Trade Center on top of the Battery Parking Garage in New York City. Tribute in Light began as a temporary commemoration of the attacks in early 2002, but it became an annual event, currently produced on September 11 by the Municipal Art Society of New York. The Tribute in Light was conceived by artists John Bennett, Gustavo Bonevardi, Richard Nash Gould, Julian LaVerdiere, and Paul Myoda, and lighting consultant Paul Marantz.

The Tribute's illumination begins at dusk and ends at dawn, with the lights being turned off for 20-minute periods to allow migratory birds to escape as needed. On clear nights, the lights can be seen from 60 miles (97 km) away, visible in all of New York City and most of suburban Northern New Jersey and Long Island. The lights can also be seen in Fairfield County, Connecticut, as well as Westchester, Orange, and Rockland counties in New York.

A slurry wall is a civil engineering technique used to build reinforced concrete walls in areas of soft earth close to open water, or with a high groundwater table. This technique is typically used to build diaphragm (water-blocking) walls surrounding tunnels and open cuts, and to lay foundations. Slurry walls are a "well-established" technology but the decision to use slurry walls for a certain project requires geophysical and other engineering studies to develop a plan appropriate for the needs of that specific location. Slurry walls may need to be used in conjunction with other methods to meet project objectives.

The September 11 attacks have had profound and wide-ranging political, economic, health and societal effects.

The attacks elicited major rescue and recovery efforts in the affected areas, in particular at the World Trade Center site, which was rebuilt to include a memorial to the victims. Many of the hundreds of workers assisting in these efforts, as well as survivors and people living and working near the site, became seriously ill in the following years and decades due to exposure to toxins, which had spread throughout New York City as a result of the Twin Towers’ collapse. Mental health problems, especially post-traumatic stress disorder (PTSD) among ordinary citizens and first responders also increased as a result of the attacks.

Daniel Libeskind (born May 12, 1946) is a Polish–American architect, artist, professor, and set designer. Libeskind founded Studio Daniel Libeskind in 1989 with his wife, Nina, and is its principal design architect.

He is known for the design and completion of the Jewish Museum in Berlin, Germany, that opened in 2001. On February 27, 2003, Libeskind received further international attention after he won the competition to be the master plan architect for the reconstruction of the World Trade Center site in Lower Manhattan.

The World Trade Center (WTC) is a complex of buildings in Lower Manhattan, New York City, replacing the original seven buildings on the same site that were destroyed during the September 11 attacks of 2001. The area is currently being redeveloped with up to six skyscrapers, four of which have been finished as of 2025; a memorial and museum is at the new plaza; which is the elevated Liberty Park adjacent to the site, containing the St. Nicholas Greek Orthodox Church and the Vehicular Security Center; the Perelman Performing Arts Center; and a transportation hub. The 104-story One World Trade Center, being the tallest building in the Western Hemisphere, is the lead building for the new complex.

The buildings are among many created by the World Trade Centers Association. The original World Trade Center including the Twin Towers, were opened in 1973 and were the tallest buildings in the world at the time of their completion. They were destroyed on the morning of September 11, 2001, when al-Qaeda members hijacked two Boeing 767 jets and flew them into the towers in a coordinated act of terrorism, killing 2,753 people. The resulting collapse of the World Trade Center caused structural failure in the surrounding buildings as well. The process of cleaning up and recovery at the World Trade Center site took eight months, after which site redevelopment commenced.

3 World Trade Center (3 WTC; also known as 175 Greenwich Street) is a skyscraper constructed as part of the new World Trade Center in Lower Manhattan, New York City. The tower is located on Greenwich Street along the eastern side of the World Trade Center site. The building was designed by Rogers Stirk Harbour + Partners, and is managed by Silverstein Properties through a ground lease with the Port Authority of New York and New Jersey (PANYNJ), the landowner. It is 1,079 ft (329 m) high, with 80 stories. As of 2025, it is the tenth-tallest building in the city.

The current edifice is the second on the World Trade Center site to bear the address 3 World Trade Center. The original building was the Marriott World Trade Center, a 22-story, 825-room hotel located in the southwest corner of the World Trade Center complex. Opened in July 1981 as the Vista International Hotel, it was destroyed during the September 11 attacks in 2001, along with the rest of the World Trade Center.

4 World Trade Center (4 WTC; also known as 150 Greenwich Street) is a skyscraper constructed as part of the new World Trade Center in Lower Manhattan, New York City. The tower is located on Greenwich Street at the southeastern corner of the World Trade Center site. Fumihiko Maki designed the 978 ft-tall (298 m) building. It houses the headquarters of the Port Authority of New York and New Jersey (PANYNJ).

The current 4 World Trade Center is the second building at the site to bear this address. The original building was a nine-story structure at the southeast corner of the World Trade Center complex. It was destroyed during the September 11 attacks in 2001, along with the rest of the World Trade Center. The current building's groundbreaking took place in January 2008, and it opened to tenants and the public on November 13, 2013. The building has 2.3 million square feet (210,000 m) of space.

The Perelman Performing Arts Center, also known as 6 World Trade Center (6 WTC) and branded as PAC NYC, is a multi-space performing arts center at the northeast corner of the World Trade Center complex in Manhattan, New York City. The Performing Arts Center is located at the intersection of Vesey, Fulton, and Greenwich Streets in Lower Manhattan. The building is named for billionaire Ronald Perelman, who donated $75 million to its construction.

Plans for the Performing Arts Center were first announced by the Lower Manhattan Development Corporation (LMDC) in 2004 as part of the rebuilding of the World Trade Center site after the September 11 attacks. Gehry Partners LLP and Snøhetta were selected as the original designers, but plans were repeatedly stalled and later scrapped. Joshua Ramus and Davis Brody Bond were selected as architects in 2015, joined by Magnusson Klemencic Associates (MKA) as the structural engineer. Below-ground construction began in August 2017, followed by the construction of the above-ground frame in 2020. The center, known during construction as the Ronald O. Perelman Performing Arts Center at the World Trade Center, opened on September 13, 2023. The Performing Arts Center includes approximately 90,000 square feet (8,400 m) across three floors.
