Once the tallest building in the world (since surpassed by a Taiwanese building), Petronas Twin Towers dominates the Malaysian capital's skyline. Most striking is the skybridge which connects the two towers about halfway up and which can be accessed for free (requires a ticket). I think the skybridge and the mirrored twins are what makes this building a truly striking sight. Interestingly, the lifts are double height, servicing two consecutive floors at the same time.
