Look out of the window from many points in Abu Dhabi at night and you could be forgiven for thinking you've had one too many at the bar: reaching skyward in the city's southeast is this 35-floor, dramatically listing skyscraper that holds the Guinness world record as the world's most leaning building (at 18 degrees westwards, it's over four times more wayward than the Leaning Tower of Pisa).
It's the focal point of the Abu Dhabi National Exhibition Centre (Adnec) and also houses a Hyatt hotel.
