Suppose The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China. It was created to protect the Chinese states and empires against the raids and invasions of the various nomadic groups of the Eurasian Steppe. The earliest known walls were built during the Spring and Autumn period (770-476 BC), while the most well-known sections were built during the Ming Dynasty (1368-1644).
Can we infer that "The Great Wall of China was built solely for aesthetic purposes"? Yes, no, or maybe?
