The Great Wall can be found in China. It is a series of fortifications built, over several dynasties, primarily to protect against invasions and raids from nomadic groups. The wall stretches thousands of miles and showcases a range of architectural styles, materials, and construction techniques, reflecting the diverse history of the regions it traverses. The most well-known sections, often visited by tourists, were built during the Ming dynasty (1368–1644). In 1987, UNESCO designated the Great Wall a World Heritage Site, recognizing its historical importance and cultural value as a symbol of China's enduring strength and resilience.
