The Wall of Benin
Created by the Edo people of the Benin Empire(1447-1897). Currently located in Benin City, Nigeria.
"They extend for some 16,000 kilometres in all, in a mosaic of more than 500 interconnected settlement boundaries. They cover 6,500 square kilometres and were all dug by the Edo people. In all, they are four times longer than the Great Wall of China, and consumed a hundred times more material than the Great Pyramid of Cheops. They took an estimated 150 million hours of digging to construct, and are perhaps the largest single archaeological phenomenon on the planet."-Fred Pearce
Yet people still maintain Africa has no significant achievements. We’ve been spoon fed bullshit all out lives.
