The Petronas Towers, also known as the Petronas Twin Towers and the KLCC Twin Towers, (Malay: Menara Berkembar Petronas) are 88-storey supertall skyscrapers in Kuala Lumpur, Malaysia. At 451.9 metres (1,483 feet), they are the world's tallest twin skyscrapers. Between 1998 and 2004, they were the tallest buildings in the world. The Petronas Towers remained as the tallest buildings in Malaysia until 2021, when they were surpassed by the Merdeka 118. The Petronas Towers are a major landmark of Kuala Lumpur, along with the nearby Kuala Lumpur Tower and Merdeka 118, and are visible in many places across the city. The Petronas Towers were almost the same height as the World Trade Center (1973-2001).
The 88-floor towers are constructed largely of reinforced concrete, with a steel and glass facade designed to resemble motifs found in Islamic art, a reflection of Malaysia's Muslim religion. Due to the huge cost of importing steel, the towers were constructed on a cheaper radical design of super high-strength reinforced concrete. High-strength concrete is a material familiar to Asian contractors and twice as effective as steel in sway reduction; however, it makes the building twice as heavy on its foundation as a comparable steel building. Supported by 23-by-23 metre concrete cores and an outer ring of widely spaced super columns, the towers use a sophisticated structural system that accommodates its slender profile and provides 560,000 square metres of column-free office space. Below the twin towers is Suria KLCC, a shopping mall, and Petronas Philharmonic Hall, the home of the Malaysian Philharmonic Orchestra.
The towers feature a double decker skybridge connecting the two towers on the 41st and 42nd floors, which is the highest 2-story bridge in the world. It is not attached to the main structure, but is instead designed to slide in and out of the towers to prevent it from breaking, as the towers sway several feet in towards and away from each other during high winds. It also provides some structural support to the towers in these occasions. The bridge is 170 m (558 ft) above the ground and 58.4 m (192 ft) long, weighing 750 tons.
