The Petronas Towers were the world’s tallest twin-tower complex when completed in 1998.
The paired skyscrapers stand in Kuala Lumpur’s City Centre and were designed by Argentine-American architect César Pelli. Their floor plans are based on Islamic geometric forms, and a skybridge connects the towers at the 41st and 42nd floors.
Each tower rises to 451.9 metres, including its pinnacle. The towers held the record for the world’s tallest buildings by architectural height until Taipei 101 surpassed them in 2004, although their twin-tower distinction remains a separate category.
A common mistake is to treat the skybridge as a structural connection between the towers at every level. It is a limited-height connection and also serves as a visitor attraction.
