PETRONAS TWIN TOWER 9 FEBRUARY 2019
The Petronas Twin Tower is an architectural wonder. It is built from hooks and plates without any cement. Hence, on a windy day the upper floors may sway.
It was the world's tallest tower until 2004 when Taipei's 101 was built, and until 2010 when Burj Khalifa was built in Dubai. However, it remains the world's tallest twin tower.
