Elmina Castle
Constructed in 1482 by the Portuguese, who called it São Jorge da Mina, Elmina Castle is the oldest existent colonial structure in Sub-Saharan Africa. It's held up beautifully throughout the centuries, but as a center for the transatlantic slave trade, much of its history is dark. We took a tour, during which we were confronted with the unthinkable conditions suffered by the prisoners, before they were shipped off to the New World.
