Tallest twin buildings

What to remember

At 170 m above the ground, level with the 41st and 42nd floors, a steel skybridge open to visitors links the two Petronas Towers in Kuala Lumpur. Opened in 1998, they rise to 452 m with 88 storeys each: the tallest twin buildings in the world.

Argentine architect César Pelli designed them, and Thornton Tomasetti handled the engineering. From 1998 to 2004 they were the tallest buildings in the world, until Taipei 101 in Taiwan overtook them. As twin skyscrapers, they surpassed the original World Trade Center towers in New York City. They were the tallest buildings in Malaysia until 2019, when The Exchange 106 overtook them.

Besides the offices of oil company Petronas, the complex houses a concert hall, a mosque, a conference centre, shops and entertainment venues.
