St George’s Castle, Popularly known as Elmina Castle is Unesco heritage site, built as a trading post by the Portuguese in 1482, and captured by the Dutch in 1637. It was expanded when slaves replaced gold as the major object of commerce, with storerooms converted into dungeons. The informative tour (included in the entry fee) takes you to the grim dungeons, punishment cells, Door of No Return and the turret room where the British imprisoned the Ashanti king, Prempeh I, for four years. Elmina Castle was the first trading post built on the Gulf of Guinea, so is the oldest European building in existence in suib-Saharan Africa. Elmina is also a picturesque fishing town along Ghana’s coast
