Cape Coast Castle is a colonial building with profound historical significance located on the coastline of Ghana. It was built in 1653 and was once one of the key centers of the British slave trade. As a UNESCO World Heritage Site, it witnessed the tragic history of thousands of African slaves being transported to the Americas. Today, Cape Coast Castle has become a museum that displays the history of the slave trade and the cultural heritage of Ghana. Visitors can visit the cells, underground passages and display areas in the fortress to learn about this painful history and feel the shock and reflection of history.
