The Petronas Towers reach a height of 451.9 metres, making them the world’s tallest twin towers.
The two skyscrapers stand in Kuala Lumpur and were completed in 1998. Argentine architect César Pelli designed them with a geometric plan based partly on Islamic motifs, including interlocking forms that create an eight-pointed star pattern.
A two-level skybridge links the towers at the 41st and 42nd floors. It is not fixed rigidly to both buildings, allowing the towers to move independently in wind. The towers contain offices, retail areas, and visitor facilities.
The Petronas Towers were briefly the world’s tallest buildings overall, but that claim depended on measuring architectural spires. Their enduring record is more specific: they remain the tallest twin buildings. They are also distinct from Kuala Lumpur Tower, a separate telecommunications structure nearby.
