Elmina Castle (Slave Fort/World Heritage Monument), (10 km west of Cape Coast), . The oldest European building below the Sahara, Elmina was a notorious slave fort used for moving slaves onto ships bound for other parts of the world. It is a tourist attraction, but once was a prison used by the Ghanaian government. It is similar in tone to a Holocaust museum, so prepare to be moved. The people in the town outside are generally friendly. However, be careful where you step if you walk on the beach. Apparently, the toilet facilities in the area are lacking.
