Everybody should visit the Elmina Castle, one of mayn castle along the coast of Ghana where the slavetrade was organised and slaves shipped to the Americas. Built originally by the portugese in 1482 as a trading place it developed into a main central for keeping slaves until they could be put of ships to go across the Atlantic. Feeling the history of tens of thousands of persons that sufferede the horros inside the castle is very emontional. The price for entry - 40 Cedis - includes a very competent guide that will take you around the main spots. The tour takes about 45 minutes.
