Elmina Castle was the first trading post built on the Gulf of Guinea, so is the oldest European building in existence in sub-Saharan Africa. Elmina is also a picturesque fishing town along Ghana’s coast, not far from Cape Coast. It is home to one of Ghana’s biggest attractions, St George’s Castle. Built by the Portuguese in 1482, it was captured by the Dutch 150 years later and became the headquarters of their West Indies Company for the following 250 years.
