| Petronas Twin Towers, The tallest twin buildings in the world |
The completion of the Petronas Twin Towers in 1998 ended the reign of Willis Tower (formerly Sears Tower) as the world's tallest building from 1973 to 1998. Unfortunately, in 2004, Taipei 101—a skyscraper in Taipei, Taiwan, with a height of 508.2 meters—surpassed the Petronas Twin Towers as the tallest building in the world. Despite losing the title of the world's tallest building, the Petronas Twin Towers still hold three unbroken world records: the World's Tallest Twin Buildings, the World's Highest Skybridge, and the World's Deepest Foundation for a building.
