Petronas Towers

Petronas Towers, twin skyscrapers in Kuala Lumpur, Malaysia, that are the world's tallest twin towers. Standing 1,483 ft (452 m) high, they were designed by the Argentinean-American architect Cesar Pelli. Completed in 1997, they surpassed Chicago's Sears Tower as the record-holding tallest structure; they themselves were surpassed by Taipei 101 in 2003. The twin towers house Petronas, Malaysia's government-owned oil company, as well as associated Malaysian firms and multinational companies. Part of a large burst of construction that marked the country's 1990s economic boom, the buildings stand at the northern end of a projected high-tech business zone, the Malaysia Multimedia Supercorridor. Built of steel-reinforced concrete columns clad in stainless steel and glass, with a design based on geometric patterns originating in ancient Islam, the 88-story buildings are connected at levels 41 and 42 by a double-decker pedestrian skybridge, and each tower is surmounted by a 242-ft-high (74-m) pinnacle. At the lower level, the Petronas Towers also include a concert hall that is home to the Malaysian Philharmonic and a business reference library.

Petronas Towers

Twin stainless-steel-clad skyscrapers, linked by a skybridge, in Kuala Lumpur, Malaysia. Designed by Cesar Pelli (b. 1926) and completed in 1998, the circular, step-tapered towers house the headquarters of Malaysia's national petroleum company. Each tower is 88 stories high, has a structural frame of high-strength, steel-reinforced concrete, and reaches a height of 1,483 ft (451.9 m)—a figure that includes a pinnacle and steel spire atop each. In 1996, after achieving their full height, the towers were considered the world's tallest buildings, surpassing the then-tallest Sears Tower; they, in turn, were superseded in 2003 by the Taipei 101 (Taipei Financial Center) building in Taipei, Taiwan, that rose to 1,667 ft (508 m).
