Take a look at the history
The continent of Africa is touted as the cradle of humanity and has played a huge part in world history. But apart from this role, the history of the continent itself is a world of knowledge on its own.
From remnants of prehistoric times, through the ages of colonization to modern times, a historical expedition to Africa will open up your mind, expose you to new worlds of knowledge and understanding and influence your perspective on various issues.
Some well-known sites are the Isimila Stone Age site in Tanzania, Telouet Kasbah of Morocco, the Pyramids of Egypt, among others.
