Great Wall of China as the name from China

the Great Wall of China is one of the most impressive architectural feats in history. Built some 2000 plus years ago and stretching approximately 4000 miles, the Chinese erected the wall to protect its northern borders from invasion. Considered the largest structure built by man, construction began in the 5th century BC and continued well into the 16th century. Historians estimate that a whopping 300,000 soldiers and 500,000 people participated in the construction.
