Elmina Castle is one of the many structures on the west coast of Africa which "warehoused" enslaved Africans before they were shipped across the Atlantic.Built by the Portuguese in 1482, it was later controlled by the Dutch (1637-1872), then the English (1872-1957). At the peak of its role in the trade in humans, over a thousand Africans were crowded into its dungeons (so small it was almost impossible for anyone to lie down) and approximately 700,000 Africans per year were shipped from the Gold Coast (Ghana) alone.
During this "warehousing," conditions for Africans were unsanitary, food was minimal, and rape of enslaved women by Europeans was routine. Such conditions continued on slave ships. It has been estimated that, for every one African who arrived in the New World, twelve had died during the process of capture, "warehousing," and the Middle Passage across the Atlantic. In 2001, the United Nations declared the Atlantic Slave Trade a "crime against humanity."
