from Wikipedia Cape Town:
Cape Town (Afrikaans: Kaapstad; Xhosa: iKapa) is the second most populous city in South Africa, forming part of the metropolitan municipality of the City of Cape Town. It is the provincial capital of the Western Cape, as well as the legislative capital of South Africa, where the National Parliament and many government offices are located. Cape Town is famous for its harbour as well as its natural setting in the Cape floral kingdom, including such well-known landmarks as Table Mountain and Cape Point. Cape Town is one of the most popular South African destinations for tourism.
Cape Town was originally developed as a victualling (supply) station for Dutch ships sailing to Eastern Africa, India, and the Far East more than 200 years before the construction of the Suez Canal in 1869. Jan van Riebeeck's arrival on 6 April 1652 established the first permanent European settlement in South Africa. Cape Town quickly outgrew its original purpose as the first European outpost at the Castle of Good Hope. It was the largest city in South Africa until the growth of Johannesburg.
According to the 2007 Community Survey, the city has a population of 3.5 million. Cape Town's land area of 2,455 square kilometres (948 sq mi) is larger than other South African cities, resulting in a comparatively lower population density of 1,425 people per square kilometre (3,689/sq mi). Cape Town is twinned with Nice in France and Haifa in Israel.
