WORLDS TALLEST BUILDING

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 (42.1 m) 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.
