Located on the shore of Table Bay, Cape Town, as the oldest urban area in the Western Cape, it was developed by the Dutch East India Company (VOC) as a supply station for Dutch ships sailing to East Africa, India, and the Far East. Jan van Riebeeck's arrival on 6 April 1652 established the VOC Cape Colony, the first permanent European settlement in South Africa. Cape Town outgrew its original purpose as the first European outpost at the Castle of Good Hope, becoming the economic and cultural hub of the Cape Colony. Until the Witwatersrand Gold Rush and the development of Johannesburg, Cape Town was the largest city in South Africa.
