Macau (also spelled Macao, traditional Chinese: 澳門 simplified Chinese: 澳门) is a Special Administrative Region (SAR) of the People's Republic of China. Located across the Pearl River estuary from Hong Kong, until 1999 Macau was an overseas territory of Portugal. One of the world's most densely populated spots, Macau generates more revenue from gambling than anywhere else on the planet, including more than seven times the revenue generated by "The Strip" in Las Vegas.
Macau was one of the earliest European colonies in Asia and the last to be relinquished (1999) and thus has a more visible colonial history than Hong Kong. Walking through the old city you could convince yourself you were in Europe - if the streets were devoid of people and signs in Chinese, that is. The Portuguese and Macanese populations continue to maintain a presence but, as expected, most of the population is native Chinese.
