Elmina Castle. This is one of the Castles you will like to consider visiting while in Ghana. This is a beautiful Castle but full of sad memories. You&amp;#8217;ll get to take a look at the dungeons that were used to hold slaves before they were shipped to Europe or America. You&amp;#8217;ll also learn  heaps of things that went on during slavery. It&amp;#8217;s a Must See.
