Dubailand is a proposed mega-theme park and tourism development in Dubai, United Arab Emirates. It is envisioned to cover 45,900 acres, three times the size of Manhattan, making it the largest theme park in the world. The development aims to attract 20 million visitors annually and diversify Dubai's economy beyond oil. Construction began in 2002 but the project was heavily delayed by the 2008 global financial crisis. Currently only a few components of the original vision have been completed, with the future of the massive project remaining uncertain.
