Skyscrapers are considered symbols of a city's money, power and, to some extent, hubris. The first building widely considered a modern skyscraper was the Wainwright Building in St. Louis. Opened in 1891 and designed by famed architect Louis Sullivan, it is ten stories tall. But with advancing technology and growing creativity, the ceaseless climb of the world's epic skyscrapers has resulted in the race to touch the sky.
The world's current tallest building is Burj Khalifa in Dubai, United Arab Emirates. It measures 2,717 feet (828 meters), or 160 stories. This record will be shattered when Kingdom Tower, a giant skyscraper planned for the Saudi Arabian city of Jeddah, is completed by 2016.
