Which is the world’s tallest spiral (twisting) tower?

Correct answer: Shanghai Tower, China. The 632 m Shanghai Tower has a twisting, spiral form and is the tallest twisted tower in the world.

Background: The spiral design reduces the force of wind on the building.

• Tokyo Skytree, Japan: Tokyo Skytree is a tall tower but is not twisted.
• Canton Tower, China: Canton Tower has a twisted lattice shape but is shorter than Shanghai Tower.
• Burj Khalifa: Burj Khalifa is the tallest building, but it is not a twisted tower.

Did you know? Shanghai Tower is the second-tallest building in the world after the Burj Khalifa.

Memory trick: Spiral tower = Shanghai.
