Westfield World Trade Center is a shopping mall at the World Trade Center complex in Manhattan, New York, that is operated and managed by Unibail-Rodamco-Westfield. The mall opened on August 16, 2016 as the largest shopping complex in Manhattan, with 125 retail spaces. It replaced the Mall at the World Trade Center, the underground shopping mall under the original World Trade Center, which was destroyed on September 11, 2001.

3 World Trade Center (also known as 175 Greenwich Street) is a skyscraper constructed as part of the rebuilding of the World Trade Center in Lower Manhattan, New York City. The tower is located on the east side of Greenwich Street, on the eastern side of the World Trade Center site. The current 3 World Trade Center is the second building at the site to bear this name. The original building was the Marriott World Trade Center, a hotel located in the southwest corner of the World Trade Center complex. The hotel was a 22-story steel-framed structure with 825 rooms. It had a roof height of 242 feet (74 m). Construction began in 1979 and it opened in July 1981 as the Vista International Hotel. The entire World Trade Center complex was destroyed during the September 11 attacks in 2001. Construction originally began in 2010, but was delayed until 2014 because of a lack of an anchor tenant. The building's concrete core was topped out to maximum height in August 2016, with the perimeter steel structure following on October 6, 2016. The building opened on June 11, 2018. 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, the landowner. It is 1,079 ft (329 m) high, with 80 stories. As of 2021, it is the ninth-tallest building in the city.

The WTC Cortlandt station (signed as World Trade Center on walls and historically known as Cortlandt Street and Cortlandt Street–World Trade Center) is a station on the IRT Broadway–Seventh Avenue Line of the New York City Subway in Lower Manhattan. The station is located under the intersection of Greenwich Street and Cortlandt Way within the World Trade Center. It is served by the 1 train at all times. The original Cortlandt Street station was built by the Interborough Rapid Transit Company (IRT) and opened in 1918 as part of the Dual Contracts. The station was renovated in the 1960s when the original World Trade Center was built. Around that time, the portion of Cortlandt Street above the station was demolished to make way for the World Trade Center. The Cortlandt Street station was destroyed on September 11, 2001. Although service on the Broadway–Seventh Avenue Line through the area was restored in 2002, the station's reconstruction was delayed until 2015 because the Port Authority of New York and New Jersey had to first rebuild the World Trade Center PATH station beneath it. After an extensive reconstruction, the Cortlandt Street station reopened on September 8, 2018, as WTC Cortlandt. The station contains connections to the PATH at the World Trade Center station, as well as an out-of-system passageway to the Chambers Street–World Trade Center/Park Place/Cortlandt Street and Fulton Street subway complexes via the World Trade Center Transportation Hub.

Cortlandt Street was an express station at Greenwich Street on the demolished IRT Ninth Avenue Line in Manhattan, New York City. It was built as a replacement for the original southern terminus at Dey Street. It had three tracks, one island platform and two side platforms. It was served by trains from the IRT Ninth Avenue Line. It closed on June 11, 1940. The next southbound stop for all trains was Rector Street. The next northbound local stop was Barclay Street. The next northbound express stop was Warren Street. The station was located two blocks from Liberty Street Ferry Terminal and Cortland Street Ferry Depot. These were the main ferry terminals for passengers traveling to Communipaw Terminal and Exchange Place Terminal in Jersey City. The site of the station was in the parcel of land acquired in the early 1970s as the location for the World Trade Center.

The World Trade Center cross, also known as the Ground Zero cross, is a formation of steel beams found among the debris of the World Trade Center site in Lower Manhattan, New York City, following the September 11 attacks in 2001. This set of beams is so named because it resembles the proportions of a Christian cross. The beams have been part of an exhibit at the National September 11 Museum since 2014.

The 1993 World Trade Center bombing was a terrorist attack on the World Trade Center in New York City, carried out on February 26, 1993, when a truck bomb detonated below the North Tower of the complex. The 1,336 lb (606 kg) urea nitrate–hydrogen gas enhanced device was intended to send the North Tower (Tower 1) crashing into the South Tower (Tower 2), bringing both towers down and killing tens of thousands of people. It failed to do so, but killed six people, including a pregnant woman, and injured over one thousand. About 50,000 people were evacuated from the buildings that day.The attack was planned by a group of terrorists including Ramzi Yousef, Mahmud Abouhalima, Mohammad Salameh, Nidal A. Ayyad, Abdul Rahman Yasin, and Ahmed Ajaj. They received $660 from Khalid Sheikh Mohammed, Yousef's uncle. In March 1994, four men were convicted of carrying out the bombing: Abouhalima, Ajaj, Ayyad, and Salameh. The charges included conspiracy, explosive destruction of property, and interstate transportation of explosives. In November 1997, two more were convicted: Ramzi Yousef, the organizer behind the bombings, and Eyad Ismoil, who drove the truck carrying the bomb.

4 World Trade Center (also known by its street address, 150 Greenwich Street) is a skyscraper that is part of the World Trade Center complex in New York City. It is located on the southeast corner of the 16-acre (6.5 ha) World Trade Center site, where the original nine-story 4 World Trade Center stood. Pritzker Prize-winning architect Fumihiko Maki was awarded the contract to design the 978 ft-tall (298 m) building. It houses the headquarters of the Port Authority of New York and New Jersey (PANYNJ).The building's groundbreaking took place in January 2008, and it opened to tenants and the public on November 13, 2013. As of 2016, it is the third tallest skyscraper at the rebuilt World Trade Center, behind One and 3 World Trade Center. However, 2 World Trade Center is expected to surpass the height of both 3 and 4 WTC upon completion. The total floor space of the building includes 1.8 million square feet (167,000 square meters) of office and retail space.

Radio Row is a nickname for an urban street or district specializing in the sale of radio and electronic equipment and parts. Radio Rows arose in many cities with the 1920s rise of broadcasting and declined after the middle of the 20th century.

4 World Trade Center was a nine-story low-rise office building completed in 1975 that was 118 ft (36 m) tall, and located in the southeast corner of the World Trade Center complex in Lower Manhattan, New York City. The building was designed by Minoru Yamasaki and Emery Roth & Sons. On September 11, 2001, the building was heavily damaged as a result of attacks carried out by the Islamic terrorist group Al-Qaeda, and was later demolished. Its site is now the location of 3 World Trade Center and a new 4 World Trade Center.

Hudson Terminal was a rapid transit station and office-tower complex in the Radio Row neighborhood of Lower Manhattan in New York City. Opened during 1908 and 1909, it was composed of a terminal station for the Hudson & Manhattan Railroad (H&M), as well as two 22-story office skyscrapers and three basement stories. The complex occupied much of a two-block site bounded by Greenwich, Cortlandt, Church, and Fulton Streets, which later became the World Trade Center site. The railroad terminal contained five tracks and six platforms serving H&M trains to and from New Jersey; these trains traveled via the Downtown Hudson Tubes, under the Hudson River, to the west. The two 22-story office skyscrapers above the terminal, the Fulton Building to the north and the Cortlandt Building to the south, were designed by architect James Hollis Wells of the firm Clinton and Russell in the Romanesque Revival style. The basements contained facilities such as a shopping concourse, an electrical substation, and baggage areas. The complex could accommodate 687,000 people per day, more than Pennsylvania Station in Midtown Manhattan. The buildings opened first, being the world's largest office buildings upon their completion, and the terminal station opened afterward. The H&M was successful until the mid-20th century, when it went bankrupt. The railroad and Hudson Terminal were acquired in 1962 by the Port Authority of New York and New Jersey, which rebranded the railroad as Port Authority Trans-Hudson (PATH). The Port Authority agreed to demolish Hudson Terminal to make way for the World Trade Center, and the railroad station closed in 1971, being replaced by PATH's World Trade Center station. While the buildings were demolished in 1972, the last remnants of the station were removed in the 2000s as part of the development of the new World Trade Center following the September 11 attacks in 2001.

World Trade Center is a terminal station on the PATH system, within the World Trade Center complex in the Financial District of Manhattan, New York City. It is served by the Newark–World Trade Center line at all times, as well as by the Hoboken–World Trade Center line on weekdays, and is the eastern terminus of both. The World Trade Center station is near the site of the Hudson and Manhattan Railroad's (H&M) Hudson Terminal, which opened in 1909. The Port Authority of New York and New Jersey bought the bankrupt H&M system in 1961, rebranded it as PATH, and redeveloped Hudson Terminal as part of the World Trade Center. The World Trade Center station opened on July 6, 1971, as a replacement for Hudson Terminal, which was closed and demolished as part of the construction of the World Trade Center. Following the September 11, 2001 attacks, a temporary PATH station opened in 2003 while the World Trade Center complex was being rebuilt. Work on a permanent station building commenced in 2008. The main station house, the Oculus, opened on March 3, 2016, and the terminal was renamed the World Trade Center Transportation Hub, or "World Trade Center" for short. The station has five tracks and four platforms in the middle of a turning loop. Trains from New Jersey use the loop to turn around and head back to New Jersey. The platforms are four floors below ground level. The floor immediately above the platforms is occupied by the station's fare mezzanine. The New York City Subway's WTC Cortlandt station is adjacent to and above the mezzanine. The $4 billion Oculus station house, designed by Spanish architect Santiago Calatrava, consists of white ribs that interlock high above the ground. The interior of the station house contains two underground floors, which house part of the Westfield World Trade Center mall. The transportation hub connects the various modes of transportation in Lower Manhattan, from the Fulton Center in the east to the Battery Park City Ferry Terminal in the west, and includes connections to various New York City Subway stations. It is the fifth-busiest transportation hub in the New York metropolitan area. The new station has received mixed reviews: although the hub has been praised for its design, it has also been criticized for its high costs and extended delays.

The Austin J. Tobin Plaza, also known as the World Trade Center Plaza, was a large public square that was located on the World Trade Center site from 1966 until its destruction during the September 11 attacks in 2001. It covered 5 acres (220,000 sq ft; 2.0 ha), making it the largest plaza in New York City by acreage at the time. The plaza opened on April 4, 1973, and was renamed after Austin J. Tobin in 1982. Several sculptures were located there, including The Sphere and Ideogram. The plaza was damaged by a car bomb in the 1993 World Trade Center bombing, and it was destroyed eight years later in the September 11 attacks.
