Massive Ring-Shaped Structure Could Encircle Dubai’s Burj Khalifa

Upon its inauguration in January 2010, Burj Khalifa easily surpassed the Taipei 101 (Taipei Financial Center) building in Taipei, Taiwan, which measured 1,667 feet (508 metres), as the world’s tallest building. At the same time, Burj Khalifa broke numerous other records, including the world’s tallest freestanding structure, the world’s highest occupied floor, and the world’s highest outdoor observation deck.
