It was built along an east-to-west line across the historical northern borders of China to protect the Chinese states and empires against invasions and raids from various nomadic groups. Construction began as early as the 7th century BC, with additions and rebuilding continuing until the 17th century AD. Stretching over 13,000 miles in length, it is a testament to the ingenuity, perseverance, and organization of ancient China. As part of the "Places/Monuments/Landmarks/Famous Monuments" hierarchy, the Great Wall embodies the grandeur and significance of renowned structures that have shaped human history and left lasting legacies for generations to enjoy and appreciate.
