Historically, the world's tallest man-made structure was the ancient tomb - the Great Pyramid of Giza in Egypt, which held the position for over 3,800 years until the construction of Lincoln Cathedral in England in 1311. Until the completion of the Washington Monument in 1884 the world's tallest buildings were Christian churches and cathedrals in Europe. The early skyscraper was pioneered in Chicago with the Home Insurance Building in 1885, forming the basis for which 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 only two buildings have held the title: Taipei 101 in 2004 and Burj Khalifa in 2010.
