HOW FAMILIAR ARE YOU WITH THE MOAT IN BENIN KINGDOM
Oba Oguola reigned in the Benin kingdom in about 1280 AD. He was responsible for digging the first and second moats (IYA) in other to fortify the city from Invaders. It took about one hundred and fifty million hours to deep. It’s said to be the second largest man-made earthwork in the world after the Great wall of China.
He further instructed that a similar moat be built around notable towns and villages in the kingdom to serve as a defensive mechanism. Twenty such moats were erected around Benin during his reign.
This is really amazing and worth seeing….
