Cape Coast Castle is one of about forty slave castles, or large commercial forts, built on the Gold Coast of West Africa (now Ghana) by European traders. It was originally a Portuguese "feitoria" or trading post, established in 1555, which they named Cabo Corso. The castle was later used in the Atlantic Slave Trade, where enslaved Africans were held before they were loaded onto ships and sold in the Americas, especially the Caribbean. The "gate of no return" was the last stop before crossing the Atlantic Ocean.
