1 World Trade Center (1970–2001) in the context of "Twin Towers"

The original World Trade Center (WTC) was a complex of seven buildings in the Financial District of Lower Manhattan in New York City. Built primarily between 1966 and 1975, it was dedicated on April 4, 1973, and was destroyed on September 11, 2001. The complex included the 110-story-tall Twin Towers, at the time of their completion the tallest buildings in the world, with the original 1 World Trade Center (the North Tower) at 1,368 feet (417 m), and 2 World Trade Center (the South Tower) at 1,362 feet (415.1 m); they were also the tallest twin skyscrapers in the world until 1996, when the Petronas Towers opened in Kuala Lumpur, Malaysia. The other buildings in the complex were the Marriott World Trade Center (3 WTC), 4 WTC, 5 WTC, 6 WTC, and 7 WTC. The complex contained 13,400,000 square feet (1,240,000 m) of office space and, prior to its completion, was projected to accommodate an estimated 130,000 people.

The core complex cost about $400 million (equivalent to $2.37 billion in 2024). David Rockefeller suggested the construction of a large office building complex to help stimulate urban renewal in Lower Manhattan, and his brother Nelson, then New York's 49th governor, signed the legislation to build it. The buildings at the complex were designed by Minoru Yamasaki. In 1998, the Port Authority of New York and New Jersey decided to privatize it by leasing the buildings to a private company to manage. It awarded the lease to Silverstein Properties in July 2001. During its existence, the World Trade Center symbolized globalization and the economic power and prosperity of the United States. Although its design was initially criticized by New Yorkers and architectural critics, the Twin Towers became an icon of New York City. It had a major role in popular culture, and according to one estimate was depicted in 472 films. The Twin Towers were also used in Philippe Petit's tightrope-walking performance on August 7, 1974. Following the September 11 attacks, mentions of the complex in various media were altered or deleted, and several dozen "memorial films" were created.

The Empire State Building is a 102-story, Art Deco-style supertall skyscraper in the Midtown South neighborhood of Manhattan, New York City, United States. The building was designed by Shreve, Lamb & Harmon and built from 1930 to 1931. Its name is derived from "Empire State", the nickname of New York state. The building has a roof height of 1,250 feet (380 m) and stands a total of 1,454 feet (443.2 m) tall including its antenna. The Empire State Building was the world's tallest building until the North Tower of the World Trade Center was topped out in 1970; following the September 11 attacks in 2001, the Empire State Building was once more New York City's tallest building until it was surpassed in 2012 by One World Trade Center. As of 2025, the building is the eighth-tallest building in New York City, the tenth-tallest completed skyscraper in the United States, and the 59th-tallest completed skyscraper in the world.

The site of the Empire State Building, on the west side of Fifth Avenue between West 33rd and 34th Streets, was developed in 1893 as the Waldorf–Astoria Hotel. In 1929, Empire State Inc. acquired the site and devised plans for a skyscraper there. The design for the Empire State Building was changed fifteen times until it was ensured to be the world's tallest building. Construction started on March 17, 1930, and the building opened thirteen and a half months afterward on May 1, 1931. Despite favorable publicity related to the building's construction, because of the Great Depression and World War II, its owners did not make a profit until the early 1950s.

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.

New York City is the most populous city in the United States, with a metropolitan area population of over 19 million as of 2025. Its skyline is one of the largest in the world, and the largest in the United States, in North America, and in the Western Hemisphere. Throughout the 20th century, New York City's skyline was by far the largest in the world. New York City is home to more than 7,000 completed high-rise buildings of at least 115 feet (35 m), of which at least 106 are taller than 650 feet (198 m). The tallest building in New York is One World Trade Center, which rises 1,776 feet (541 m). The 104-story skyscraper also stands as the tallest building in the United States, the tallest building in the Western Hemisphere, and the seventh-tallest building in the world.

The city is home to many of the earliest skyscrapers, which began to appear towards the end of the 19th century. A major construction surge in the 1920s saw the completion of some of the tallest skyscrapers in the world at the time, including the Chrysler Building in 1930 and the Empire State Building in 1931 in Midtown Manhattan. At 1,250 feet (381 m) and 102-stories, the Empire State Building stood as the tallest building in the world for almost four decades; it remains among the city's most recognizable skyscrapers today. Following a lull in skyscraper development during the 1930s to 1950s, construction steadily returned. The Empire State Building was dethroned as the world's tallest building in 1970, when the 1,368-foot (417 m) North Tower of the original World Trade Center surpassed it. The North Tower, along with its twin the South Tower, held this title only briefly as they were both surpassed by the Willis Tower (then Sears Tower) in Chicago in 1973. The Twin Towers remained the tallest buildings in New York City until they were destroyed in the September 11 attacks in 2001.
