If you don't plan on visiting the Petronas Twin Towers, you better have a perfectly good explanation as to why. The iconic towers deserve a visit and a couple of pictures from your phone. Completed in 1998, these towers were once named to be the tallest in the world, however, since Burj Khalifa won the race of being the tallest building the world, the Petronas Twin Towers are said to be the tallest twin structures in the world. Featuring 88 storeys, both towers are joined at the 41st and 442nd floors by double deck Sky Bridge, which measures to about 58 meters in length. Next to the towers, you'll find a glittering mall and a park as well as a convention center and an art gallery located in close proximity.
