The Walls of Benin were a combination of ramparts and moats, called Iya in the local language[which?], used as a defense of the ancient Kingdom of Benin, which is present-day Benin City, the capital of present-day Edo, Nigeria. It was considered the largest man-made structure lengthwise and was hailed as the largest earthwork in the world. It is larger than Sungbo's Eredo.[1] It enclosed 6,500 square kilometres (2,500 sq mi) of community lands. The combined length of the walls, many of which were outside the city, was over 16,000 kilometres (9,900 miles). It was estimated that earliest construction began in 800 and continued into the mid-15th century.
