The Petronas Twin Towers in Kuala Lumpur were the world’s tallest buildings before being surpassed in 2004 by Taipei 101. However, the towers are still the tallest twin buildings in the world. 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. The Petronas Twin Towers feature a sky bridge between the two towers on the 41st and 42nd floors.
