Chiamaka Obi's post on Goodwall - The Benin moat also known as the walls of Benin is a vast system of earthworks surrounding the Benin City in Nigeria. These complex structures constructed with incredible effort using primarily mud provided a defensive advantage to the kingdom's army. The primary purpose of the Benin moat system was to protect the ancient city and its Palace from invaders. The system's total length is greater than that of the great walls of China,covering a vast area of the kingdom. #BestPhoto2025
