The Empire State Building is a 102-story skyscraper located in Midtown Manhattan, New York City, at the intersection of Fifth Avenue and West 34th Street. It has a roof height of 1,250 feet (381 meters), and with its antenna spire included, it stands a total of 1,454 ft (443.2 m) high.[6] Its name is derived from the nickname for New York, the Empire State. It stood as the world's tallest building for 40 years, from its completion in 1931 until construction of the World Trade Center's North Tower was completed in 1972. Following the September 11 attacks in 2001, the Empire State Building was again the tallest building in New York (although it was no longer the tallest in the US or the world). The Empire State Building was once again demoted to second-tallest building in New York on April 30, 2012, when the new One World Trade Center reached a greater height.[10] The Empire State Building is currently the third-tallest completed skyscraper in the United States (after the Willis Tower and Trump International Hotel and Tower, both in Chicago), and the 22nd-tallest in the world (the tallest now is Burj Khalifa, located in Dubai). It is also the fourth-tallest freestanding structure in the Americas.

One World Trade Center (1 WTC) is the primary building of the new World Trade Center complex in Lower Manhattan, New York City, New York. The 104-story supertall skyscraper stands on the northwest corner of the 16-acre World Trade Center site, occupying the location of what use to be the original 6 World Trade Center. The building is bordered to the west by West Street, to the north by Vesey Street, to the south by Fulton Street, and to the east by Washington Street. Construction on below-ground utility relocations, footings, and foundations for the building began on April 27, 2006. The tower's steel structure topped out on August 30, 2012. One World Trade center was completed on May 2, 2013, and became the tallest building in the Western Hemisphere and the third-tallest building in the world by pinnacle height, with its spire reaching a symbolic 1,776 feet (541.3 m) in commemoration of the year of American independence. It has been the tallest building in New York City since April 30, 2012. On March 30, 2009, the Port Authority of New York and New Jersey confirmed that the building will be known by its legal name, One World Trade Center, rather than the colloquial name, Freedom Tower. The new World Trade Center complex will also feature three other high-rise office buildings, located along Greenwich Street, and the National September 11 Memorial & Museum, located just south of One World Trade Center, where the Twin Towers once stood. The construction is part of an effort to memorialize and rebuild following the destruction of the original World Trade Center complex during the terrorist attacks of September 11, 2001.
