Spend time in Abu Dhabi and you'll soon discover that its residents are only too keen to tell you about the latest architectural record to be broken in the region. It feels as if every new development in Abu Dhabi is designed with the sole aim of outdoing an existing one – usually in Dubai, which so far has the world's tallest building and the world's highest hotel. Not to be outdone, Abu Dhabi's Capital Gate building boasts of having the greatest deliberate lean of any building in the world. The 35 floor building has a 18degree tilt, five times greater than that of the Leaning Tower of Pisa. To accomplish this (which has no purpose other than aesthetic) the entire 17th floor is a giant reservoir, to counteract the lean. Other feathers in Abu Dhabi's cap are the word's largest indoor theme park (Ferrari World Abu Dhabi) and the world's highest suspended penthouse suite (245m above the ground at Gate Towers), a room apparently favoured by Lewis Hamilton when he's in town.
