9. Capital Gate, United Arab Emerates
There’s some competitive architecture going on in the UAE’s building boom, each one trying to do the next in terms of size or flair (or budget, for that matter). Abu Dhabi’s 35 story Capital Gate skyscraper is not only one of the tallest buildings in the city but it leans a striking 18 degrees to the west – four times greater than paltry Pisa. It also swoops and contorts in a spiralling funnel shape. It’s a strange yet beautiful design that is becoming an iconic part of the Abu Dhabi skyline.
