Abu Dhabi is the federal capital and center of government in the United Arab Emirates. It is the largest city of the Emirate of Abu Dhabi and one of the most modern cities in the world. With a population of just under 1.5 million, Abu Dhabi is the headquarter of numerous oil companies and embassies. With only 420,000 citizens in the entire emirate, each has a theoretical net worth of $17 million, and Abu Dhabi has been described by CNN as the richest city in the world. The city features large gardens and parks, green boulevards lining all the streets and roads, sophisticated high-rise buildings, international luxury hotel chains and opulent shopping malls. Long viewed as a staid bureaucratic outpost entirely lacking in neighboring Dubai's pizazz, things started to change radically in 2004 after long-ruler Sheikh Zayed passed away and his son Sheikh Khalifa took over. In a bid to attract tourism and investment, land sales to foreigners were allowed, restrictions on alcohol were loosened and several massive projects are under way, such as the upcoming $28 billion cultural zone of Saadiyat Island and its centerpieces the Guggenheim and Louvre Museums scheduled to open in 2011. It remains to be seen how well the strategy will work, but the city is certainly experiencing a construction boom.
