Title: List of tallest buildings
Content:  Historically, the world's tallest man-made structure was the Great Pyramid of Giza in Egypt, which held the position for over 3,800 years until the construction of Lincoln Cathedral in 1311. The Strasbourg Cathedral in France, completed in 1439, was the world's tallest building until 1874. The first skyscraper was pioneered in Chicago with the 138 ft Home Insurance Building in 1885. The United States would hold the position of the world's tallest building throughout the 20th century until 1998, when the Petronas Towers were completed. Since then, two other buildings have gained the title: Taipei 101 in 2004 and Burj Khalifa in 2010. Since the beginning of the 21st century, the Middle East, China, and Southeast Asia have experienced booms in skyscraper construction.
Title: History of the world's tallest buildings
Content:  The tallest building in the world, as of 2022, is Burj Khalifa. The title of "world's tallest building" has been borne by various buildings, such as the Rouen Cathedral, the Empire State Building and the original World Trade Center. The skyscraper was invented in Chicago in 1884 when the Home Insurance Building was constructed using a steel-frame with curtain walls instead of load-bearing walls. For the next hundred years, the world's tallest building was always in the United States with New York City accumulating 86 years, and Chicago accumulating 30 years. After just over a century (1885–1998), the distinction moved to the Eastern Hemisphere. Malaysia was the first country to break the United States' record of constructing the tallest buildings in the world when the Petronas Twin Towers were completed in 1998. Taiwan's

That was in turn surpassed by the 1368 ft twin towers of New York’s original World Trade Center in 1972, which were in turn surpassed by the Sears Tower in Chicago in 1974. Now called the Willis Tower (since 2009) it was 1451 ft to its flat rooftop, or 1518 ft including its original antennas. But in 1978 One World Trade Center (commonly known as the north tower) attained a taller absolute height when it 
Title: History of the world's tallest buildings
Content:  Taipei 101 were never the world's tallest buildings by the highest–tip criterion. Since 2010, Burj Khalifa has been the tallest building by any criterion. It has the highest architectural element, tip and occupied floor, and is indeed the tallest structure of any kind ever built, surpassing the (now destroyed) 646.38 m Warsaw radio mast. Since the completion of the Washington Monument in 1884, the world's tallest building has not usually also been the world's tallest structure. The exceptions are 1930–1954, when the Chrysler Building and then the Empire State building surpassed the Eiffel Tower (to be surpassed in turn by a succession of broadcast masts, starting with the Griffin Television Tower in Oklahoma), and from 2010 with the completion of Burj Khalifa.

Content:   The world's tallest man-made structure is the 828 m Burj Khalifa in Dubai (of the United Arab Emirates). The building gained the official title of "tallest building in the world" and the tallest self-supported structure at its opening on January 9, 2010. Burj Khalifa was developed by Emaar properties, designed by Skidmore, Owings and Merrill and built by BESIX, Samsung Construction and Arabtec. The second-tallest self-supporting structure and the tallest tower in the world is the Tokyo Skytree. The tallest guyed structure is the KVLY-TV mast. The Council on Tall Buildings and Urban Habitat, an organization that certifies buildings as the "World's Tallest", recognizes a building only if at least 50% of its height is made up of floor plates containing habitable floor area. Structures that do not meet this criterion, such as the CN Tower, are defined as "towers". There are dozens of radio and television broadcasting towers which measure over 600 metres (about 2,000 ft) in height, and only the tallest are recorded in publicly available information sources.

Content:  The earliest structures now known to be the tallest in the world were the Egyptian pyramids, with the Great Pyramid of Giza, at an original height of 146.5 m, being the tallest structure in the world for over 3,800 years, until the construction of Lincoln Cathedral in 1311. From then until the completion of the Washington Monument (capped in 1884) the world's tallest buildings were churches or cathedrals. Later, the Eiffel Tower and, still later, some radio masts and television towers were the world's tallest structures. However, though all of these are structures, some are not buildings in the sense of being regularly inhabited or occupied. It is in this sense of being regularly inhabited or occupied that the term "building"

The first completed 417 m tall World Trade Center tower became the world's tallest building in 1972. However, it was overtaken by the Sears Tower (now Willis Tower) in Chicago within two years. The 442 m tall Sears Tower stood as the world's tallest building for 24 years, from 1974 until 1998, until it was edged out by 452 m Petronas Twin Towers in Kuala Lumpur, which held the title for six years.

Before the modern skyscraper era, many Christian churches and cathedrals, built mainly in England and Germanic territories between c. undefined 1250–1894, comprised the tallest buildings in the world. Before the 13th century, the tallest buildings in the world cannot be conclusively determined. For instance, the Lighthouse of Alexandria (completed about 280 BC) has been estimated to be 100 m tall, but its true height is not known. For thousands of years, the Great Pyramid in Egypt was the tallest structure in the world, but the Great Pyramid is not considered a building since it is not habitable. Similarly, the Eiffel Tower was the world's tallest structure from 1889, when it was built, until 1930, when the Chrysler Building was built.
