Trump Taj Mahal, Atlantic City: $2.3 billion (£1.7bn)
Once described by Donald Trump as “the eighth wonder of the world”, the Taj Mahal hotel and casino in Atlantic City cost $1.2 billion (£930m) to build in 1990. The blingy 120,000 square foot complex eventually became unprofitable and shut for good in October 2016, but has since reopened as the Hard Rock Hotel & Casino.
