America's Response Monument

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.

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.

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.On clear nights, the lights can be seen from over 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.The two beams cost approximately $1,626 (assuming $0.11 per kWh) to run for 24 hours. The 88 xenon spotlights (44 for each tower) each consume 7,000 watts. As of 2011, the annual cost for the entire project was about half a million dollars.Due to the COVID-19 pandemic and the perceived need for social distancing, it was originally announced that the installation would not light up on the 19th anniversary of the attacks in September 2020, for the first time since its creation. New York Governor Andrew Cuomo later announced that the state would provide health care personnel and supervision to allow the tribute to be held as scheduled.

130 Cedar Street, formerly known as the Green Exchange Building, is a mid-rise building in the Financial District of Lower Manhattan, New York City. It is located between Cedar Street and Albany Street running along Washington Street, sharing a block with 90 West Street. It was built in 1931 and was designed by Renwick, Aspinwall & Guard.

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.

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.

United Airlines Flight 175 was a domestic passenger flight that was hijacked by five al-Qaeda terrorists on September 11, 2001, as part of the September 11 attacks. The flight's scheduled plan was from Logan International Airport, in Boston, Massachusetts, to Los Angeles International Airport, in Los Angeles, California. The Boeing 767-200 aircraft was deliberately crashed into the South Tower of the World Trade Center in New York City, killing all 65 people aboard and an unknown number in the building's impact zone. Approximately thirty minutes into the flight, the hijackers forcibly breached the cockpit and overpowered the captain and first officer, allowing lead hijacker and trained pilot Marwan al-Shehhi to take over the controls, after murdering Captain Victor Saracini from Yardley, Pennsylvania and First Officer Michael Horrocks from Glen Mills, Pennsylvania. Unlike Flight 11, whose transponder was turned off, Flight 175's transponder was visible on New York Center's radar, which depicted the aircraft's deviation from its assigned flight path for four minutes before air traffic controllers took notice at 08:51 EDT. Thereafter, they made several unsuccessful attempts to contact the cockpit. Several passengers and crew members aboard made phone calls to family members and relayed information regarding the hijackers and casualties suffered by passengers and crew. The aircraft crashed into Tower Two (the South Tower) of the World Trade Center at 09:03. The Flight 175 hijacking was coordinated with that of American Airlines Flight 11, which struck the upper floors of Tower One (the North Tower) 17 minutes earlier. The crash of Flight 175 into the South Tower was the only impact televised live around the world. The crash and subsequent fire caused the South Tower to collapse 56 minutes later at 09:59, resulting in hundreds of additional casualties. During the recovery effort at the World Trade Center site, workers uncovered and identified remains from some Flight 175 victims, but many other body fragments could not be identified.

The Deutsche Bank Building (formerly Bankers Trust Plaza) was a 39-story office building located at 130 Liberty Street in Manhattan, New York City, adjacent to the World Trade Center site. The building opened in 1974 and closed following the September 11 attacks in 2001, due to contamination that spread from the collapse of the South Tower. The structure was designed by Shreve, Lamb & Harmon, which also designed the Empire State Building. The building was purchased by Deutsche Bank when it acquired Bankers Trust in 1998. It was part of the skyline of Lower Manhattan, and was demolished between 2007 and 2011. 5 World Trade Center will eventually replace the building, expanding the ground space on which the World Trade Center stands, as this land was not part of the original World Trade Center.

The Washington Street Plaza was a pedestrian plaza along Washington Street between Carlisle and Albany Streets on the west side of the Financial District in Lower Manhattan. It opened on May 23, 2013.With an epoxy gravel placed over the street, it contained granite blocks, red chairs, tables, and potted plants.Its construction was delayed for several years and debated within Manhattan Community Board 1, although it was ultimately approved by the executive committee. The Alliance for Downtown New York, the Business Improvement District led by Elizabeth H. Berger, argued that the plaza would, according to the Downtown Express, "improve pedestrian mobility" around the September 11 Memorial and allow the Alliance to install a tourist kiosk. Referring to the Alliance's report "Five Principles for Greenwich South," which advocated for the plaza, she said: “One of the things that we looked at was how to capitalize on the old-world geometry of the street plan to create a sense of destination and gathering places.... There’ll be an attractive space not only for visitors but for people who live and work in the area to congregate.” Some residents believed, however, that "it would disrupt traffic and complicate an already crowded area."The administration of former Mayor Michael Bloomberg, through Jeffrey Mandel, an adviser to Deputy Mayor Robert K. Steel, also advanced that the plaza would benefit residents of the Downtown neighborhood while helping to mitigate foot traffic from tourists. He said, "[the plaza] pushes a couple of big dominos forward by creating a place that's not just attractive and desirable for the folks down here but that has beneficial impacts in the way of mitigation."The plaza's construction was delayed by Hurricane Sandy. Representing the exiting Bloomberg administration, Mandel said, "We think it's important to make our best efforts in our last hours in the neighborhood."Activists for the recognition of the history of the Lower West Side and the Little Syria neighborhood have argued that the plaza would be an ideal place for historical signage. In anticipation of its construction, they pursued a resolution in support of signage from Community Board 1.

W New York - Downtown Hotel and Residences is a 630-foot-tall building (190 m) at 8 Albany Street in the Financial District of Lower Manhattan in New York City. The 58-story building was completed in 2010, and is tied with two other buildings, Home Insurance Plaza and the W.R. Grace Building as the 106th tallest building in New York. It is divided between a 217-room hotel, on floors 5-22, and 223 luxury residential condominiums, on floors 23-56, with lobbies for both on floors 1-4. There is a residential observation deck on the 57th floor, with views of the Hudson River, and a terrace on the 58th floor with panoramic views of lower Manhattan.

The hotel opened on August 18, 2010.In 2010, the building was featured in a HGTV contest in which a $1.5 million apartment was given to the winner as a prize.In July 2020, it was announced that the hotel would close on October 13, 2020, due to the COVID-19 pandemic; the residential units remained open but lost access to the hotel's amenities.

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.

5 World Trade Center (also referred to as 130 Liberty Street) is a planned skyscraper at the World Trade Center in Lower Manhattan, New York City. The site is across Liberty Street, to the south of the main 16-acre (6.5 ha) World Trade Center site. In February 2021 it was announced the new 5 World Trade Center will be developed in a joint venture between Silverstein Properties and Brookfield Properties. The proposed building shares its name with the original 5 World Trade Center, which was heavily damaged as a result of the collapse of the North Tower during the September 11 attacks and was later demolished. In June 2007, JPMorgan Chase announced plans to develop the building as the headquarters of its J.P. Morgan Investment Bank. However, JPMorgan Chase's acquisition of Bear Stearns in March 2008 put those plans in doubt, given the company will relocate J.P. Morgan to 383 Madison Avenue. In June 2019, the Port Authority and Lower Manhattan Development Corporation agreed to a joint RFP for the site.As of February 2021, a new design has been announced for the new 5 World Trade Center to be developed by Silverstein Properties and Brookfield Properties. The new design calls for a 1,560,000 square feet (145,000 m2) mixed-use 900-foot-tall (270-meter) tower.
