The Petronas Towers, twin skycrapers in Kuala Lumpur, Malaysia, standing 1,483 ft (452) high. They were completed in 1997 after a seven year build and became the tallest building in the world on the date of completion. They surpassed Chicago's Sears Tower as the record-holding tallest structure. Petronas Towers were the tallest building in the world from 1998 to 2004 until surpassed by Taipei 101, but remain the tallest twin buildings in the world. The building is the landmark of Kuala Lumpur.
The 88 - story towers feature a skybridge between the two towers on 41st and 42nd floors, which is the highest 2-storey bridge in the world. It is not attached to the main structure but instead designed t slide in and out of the towers to prevent it from breaking during high winds. The bridge is 588 ft(170 m) above the ground and 190 ft (58 m) long, weighing 750 tons.
Today, Petronas Twin Towers are owned and operated by Petronas, the Malaysia's government-owned oil company. Besides a 6 storey shopping complex(Suria KLCC), the twin towers house Petronas, as well as associated Malaysian firms and multinational companies. At the lower level, the Petronas Towers also include a concert hail that is home to the Malaysian Philharmonic and a business reference library.
