Leaning Skyscraper

Abu Dhabi is famous for its extreme engineering, but now one project could surpass them all - the world's most inclined skyscraper, Capital Gate. Capital Gate is a tower that spirals out of the ground at 525 feet and tilts almost five times more than the Leaning Tower of Pisa. The tower will include a five-star hotel on the top 18 levels, an infinity pool, a restaurant hanging 300 feet above the ground and a helicopter pad on the roof.
