Tribute in Light

Liberty Park is a one-acre (4,000 m2) elevated public park at the World Trade Center in Manhattan, New York City, overlooking the National September 11 Memorial & Museum in Lower Manhattan. The park, which opened on June 29, 2016, is located above the World Trade Center's Vehicular Security Center. The St. Nicholas National Shrine is located within the park, as well as Fritz Koenig's The Sphere, the iconic sculpture salvaged from the World Trade Center site. Another statue, America's Response Monument, is also located in the park.

Liberty Street Ferry Terminal or Liberty Street Terminal was the Central Railroad of New Jersey's passenger ferry slip in lower Manhattan, New York City and the point of departure and embarkation for passengers travelling on the Central Railroad of New Jersey, Baltimore and Ohio Railroad, Reading Railroad and the Lehigh Valley Railroad from the Communipaw Terminal across the Hudson River in Jersey City.

America's Response Monument, subtitled De Oppresso Liber, is a life-and-a-half scale bronze statue in Liberty Park overlooking the National September 11 Memorial & Museum in New York City. Unofficially known as the Horse Soldier Statue, it is the first publicly accessible monument dedicated to the United States Special Forces. It was also the first monument near Ground Zero to recognize heroes of the September 11 terrorist attacks.The statue was conceived by sculptor Douwe Blumberg and first sold in 2003 as a small-scale, 18 inches (460 mm) version. In April 2011, an anonymous group of Wall Street bankers who lost friends in the 9/11 attacks commissioned a large, 16 feet (4.9 m) tall version. It was dedicated on Veteran's Day, November 11, 2011, in a ceremony led by Vice President Joe Biden and Lt. Gen. John Mulholland, commander of Task Force Dagger and U.S. Army Special Operations Command during Operation Enduring Freedom.The statue commemorates the service members of America's Special Operations forces and their response to 9/11, including those who fought during the first stages of the Afghanistan war. This operation led to the initial defeat of the Taliban in Afghanistan, although the Taliban would ultimately be victorious following their 20-year-long war with the United States.

The Sphere (officially Große Kugelkaryatide N.Y., also known as Sphere at Plaza Fountain, WTC Sphere or Koenig Sphere) is a monumental cast bronze sculpture by German artist Fritz Koenig (1924–2017).The world's largest bronze sculpture of modern times stood between the twin towers on the Austin J. Tobin Plaza of the World Trade Center in New York City from 1971 until the September 11, 2001, attacks. The work, weighing more than 20 tons, was the only remaining work of art to be recovered largely intact from the ruins of the collapsed twin towers. After being dismantled and stored near a hangar at John F. Kennedy International Airport, the sculpture was the subject of the 2001 documentary Koenig's Sphere. Since then, the bronze sphere has become a memorial for the attacks. The spherical caryatid was installed in Battery Park between 2002 and 2017, when the Port Authority of New York and New Jersey moved it back close to its original location. Having become a major tourist attraction, the sculpture was rededicated at its permanent location on August 16, 2017, although the sculpture was not restored. The Sphere is installed in Liberty Park, overlooking the September 11 Memorial and its original location.

Cortlandt Street Ferry Depot was the main ferry terminal of the Pennsylvania Railroad and the West Shore Railroad on the North River (Hudson River) in lower Manhattan. The railroads operated ferries to their terminal stations on the Hudson River waterfront in New Jersey at Exchange Place and Weehawken, respectively. The depot was next to Liberty Street Ferry Terminal from which the Central Railroad of New Jersey operated its Communipaw ferry to Communipaw Terminal.

The St. Nicholas Greek Orthodox Church, officially the St. Nicholas Greek Orthodox Church and National Shrine, is a church and shrine under construction in the World Trade Center in Manhattan, New York City. It is administered by the Greek Orthodox Archdiocese of America and is being developed by the Port Authority of New York and New Jersey, based on the design of Spanish architect Santiago Calatrava. The church is set to be completed in April 2022, coinciding with the Orthodox Holy Week, and will be consecrated July 4, 2022.St. Nicholas will replace the original church of the same name that was destroyed during the September 11 attacks in 2001—the only house of worship, and only building outside the original World Trade Center complex, to be completely destroyed. The new church is located in Liberty Park, overlooking the National September 11 Memorial & Museum. Its architecture draws from Byzantine influences, namely the Church of the Savior and the Hagia Sophia in Istanbul, as well as from the Parthenon in Athens. In addition to serving as a Greek Orthodox parish, St. Nicholas is officially planned as a "House of Prayer for all people" that will function as a national shrine and community center, incorporating a secular bereavement space, social hall, and various educational and interfaith programs.Initially scheduled to open in 2016, St. Nicholas' rebuilding effort was beset by delays, cost overruns, and claims of financial impropriety. In 2019, the nonprofit Friends of St. Nicholas was founded to help complete the project, which continued under the auspices of the newly elected Archbishop Elpidophoros. The church was partially opened for a memorial service commemorating the 20th anniversary of the September 11 attacks.

90 West Street (previously known as the West Street Building and the Brady Building) is a 23-story residential building in the Financial District of Lower Manhattan in New York City. Located on West Street just south of the World Trade Center, the building was designed by Cass Gilbert, with Gunvald Aus and Burt Harrison as structural engineers, and John Peirce as general contractor. It was erected for the West Street Improvement Corporation, led by transportation magnate Howard Carroll. The Gothic styling and ornamentation of 90 West Street served to emphasize its height. The design combined elements of the three-section "classical column" arrangement of 19th-century buildings with the "romantic tower" of Gilbert's later structures such as the Woolworth Building. Its waterfront site necessitated the installation of pilings deep into the ground. Other features included a terracotta facade with granite at the two-story base, as well as terracotta fireproofing inside the building. The building's design was widely praised when it was originally completed. The building is a New York City designated landmark and listed on the National Register of Historic Places. 90 West Street was built in 1905–1907 as an office building called the West Street Building. "The Garret Restaurant", on the structure's top floors, was marketed as the highest restaurant in the world. The building underwent numerous ownership changes in the 20th century, and was known after its long-term owner, Brady Security and Realty Corporation, during the middle of the century. Following the collapse of the adjacent World Trade Center in the September 11, 2001, attacks, the West Street Building was severely damaged. The building was subsequently extensively refurbished and it reopened as a residential building called 90 West in 2005.

The construction of the first World Trade Center complex in New York City was conceived as an urban renewal project to help revitalize Lower Manhattan spearheaded by David Rockefeller. The project was developed by the Port Authority of New York and New Jersey. The idea for the World Trade Center arose after World War II as a way to supplement existing avenues of international commerce in the United States. The World Trade Center was originally planned to be built on the east side of Lower Manhattan, but the New Jersey and New York state governments, which oversee the Port Authority, could not agree on this location. After extensive negotiations, the New Jersey and New York state governments agreed to support the World Trade Center project, which was built at the site of Radio Row in the Lower West Side of Manhattan, New York City. To make the agreement acceptable to New Jersey, the Port Authority agreed to take over the bankrupt Hudson & Manhattan Railroad, which brought commuters from New Jersey to the Lower Manhattan site and, upon the Port Authority's takeover of the railroad, was renamed PATH. The Port Authority hired architect Minoru Yamasaki, who came up with the specific idea for twin towers. The towers were designed as framed tube structures, which provided tenants with open floor plans, uninterrupted by columns or walls. This was accomplished using numerous closely spaced perimeter columns to provide much of the strength to the structure, along with gravity load shared with the core columns. The elevator system, which made use of sky lobbies and a system of express and local elevators, allowed substantial floor space to be freed up for use as office space by making the structural core smaller. The design and construction of the World Trade Center, most centrally its twin towers, involved many other innovative techniques, such as the slurry wall for digging the foundation, and wind tunnel experiments. Construction of the World Trade Center's North Tower began in August 1968, and the South Tower in 1969. Extensive use of prefabricated components helped to speed up the construction process. The first tenants moved into the North Tower in December 1970 and into the South Tower in January 1972. Four other low-level buildings were constructed as part of the World Trade Center in the early 1970s, and the complex was mostly complete by 1973. A seventh building, 7 World Trade Center, was opened in 1987.

The National September 11 Memorial & Museum (also known as the 9/11 Memorial & Museum) is a memorial and museum in New York City commemorating the September 11, 2001 attacks, which killed 2,977 people, and the 1993 World Trade Center bombing, which killed six. The memorial is located at the World Trade Center site, the former location of the Twin Towers that were destroyed during the September 11 attacks. It is operated by a non-profit institution whose mission is to raise funds for, program, and operate the memorial and museum at the World Trade Center site. A memorial was planned in the immediate aftermath of the attacks and destruction of the World Trade Center for the victims and those involved in rescue and recovery operations. The winner of the World Trade Center Site Memorial Competition was Israeli-American architect Michael Arad of Handel Architects, a New York- and San Francisco-based firm. Arad worked with landscape-architecture firm Peter Walker and Partners on the design, creating a forest of swamp white oak trees with two square reflecting pools in the center marking where the Twin Towers stood. In August 2006, the World Trade Center Memorial Foundation and the Port Authority of New York and New Jersey began heavy construction on the memorial and museum. The design is consistent with the original master plan by Daniel Libeskind, which called for the memorial to be 30 feet (9.1 m) below street level—originally 70 feet (21 m)—in a plaza, and was the only finalist to disregard Libeskind's requirement that the buildings overhang the footprints of the Twin Towers. The World Trade Center Memorial Foundation was renamed the National September 11 Memorial & Museum in 2007.A dedication ceremony commemorating the tenth anniversary of the attacks was held at the memorial on September 11, 2011, and it opened to the public the following day. The museum was dedicated on May 15, 2014, with remarks from then mayor of New York City Michael Bloomberg and then President Barack Obama. Six days later, the museum opened to the public.

William G. Biggart (July 20, 1947 – September 11, 2001) was an American freelance photojournalist and a victim of the September 11 attacks, notable for his street-view photographs of the event before being killed by the collapse of the World Trade Center's North Tower. He was the only professional photographer to be killed while covering the attacks.On September 15, 2001, Biggart's remains were discovered along with a bag containing his three cameras and the CompactFlash card from which his last photographs were recovered. The photos were used in the October 15, 2001 issue of Newsweek. His photographs from 9/11 were exhibited at the International Center of Photography and the Smithsonian's National Museum of American History. They have also been preserved on the Internet by The Digital Journalist.

200 Liberty Street, formerly known as One World Financial Center, is a skyscraper in Lower Manhattan, New York City. It is located at 200 Liberty Street between South End Avenue and West Street. It was built in 1985 as part of the World Financial Center complex. It is a 40-story building reaching the height of 577 feet (176 m). It has a leasable area of 1,628,000 square feet (151,200 m2). Similarly to other WFC buildings it has a unique roof which is a truncated square pyramid. It is connected to the rest of the complex by a skybridge over Liberty Street. The building is located across the street from the World Trade Center site and was significantly damaged in the September 11 attacks. The initial dust cloud and other explosions shattered many windows, heavily damaging nearby Winter Garden Atrium and other buildings of the World Financial Center complex. It was closed for several months and reopened in 2002 after extensive restoration. It was renamed 200 Liberty Street when the rest of the complex became Brookfield Place in 2014.

Hotel Attraction was a proposal by architect Antoni Gaudí for a skyscraper in Lower Manhattan, New York City.
