The Benin Moat, also known as the Benin City Moat, is a historical earthwork that surrounds the ancient city of Benin City in present-day Nigeria. Constructed in the 15th century, it served as a defensive structure to protect the city from invaders. The moat is part of a larger system of walls and ditches that once encircled the city, showcasing the engineering skills of the Benin Kingdom. The moat stretches for several kilometers and is a significant feature of the Benin Empire's architectural heritage. It reflects the strategic importance of Benin City during its peak and is recognized as a UNESCO World Heritage site, highlighting its cultural and historical significance.
