Ghana is home to the largest concentration of slave trading forts and castles in West Africa. Many of these historic structuresโonce used by European powers as trading posts and holding cellsโstill stand along Ghanaโs coastline as haunting reminders of this dark chapter in global history.
Among them is Cape Coast, located in the Central Region of Ghana, which was a key hub during both the slave trade and the colonial era. During British rule, Cape Coast served as the colonial capital until the administrative seat was moved to Accra in the late 19th century. Today, Cape Coast Castle and nearby Elmina Castle are UNESCO World Heritage Sites and powerful symbols of remembrance and reflection.
