Great Zimbabwe, Africa
In a country where people still live in mud huts, the Great Zimbabwe Fortress, whose walls are about 5 m thick and 10 m high, erected in 1130, is a delight and amazement.
The ancient city was supposedly built from several million blocks of stone, so carefully fitted that they are still standing today without mortar!
What is also surprising is that all the structures are not rectangular, but consist of flowing curves and ovals.
Scientists are still arguing about the purpose of the huge cone-shaped tower, which has no windows or doors.
Perhaps this mysterious tower once served as a haven for the creator of all things on this earth, the supreme god Mwari?
