Capital Gate, Abu Dhabi
Leaning strikingly westward, the Capital Gate has a slope almost five times that of the Leaning Tower of Pisa. Of course, the difference here is that it was engineered to do so – it now claims the Guinness World Record as the “world’s furthest-leaning man-made tower”. The Capital Gate, opened in 2011, houses a cantilevered tea lounge, an open-air pool deck and a Hyatt hotel.
