About this subject

The Great Wall of China, a UNESCO World Heritage site since 1987, is a series of fortifications built across several dynasties, primarily the Ming (1368, 1644). Spanning over 21,000 km, it winds from Jiayuguan Pass in the west to the Yellow Sea coast at Shanhaiguan. Its main purpose was to protect the Chinese empire from nomadic invasions, especially by Mongols and Manchus. Famous sections like Badaling and Mutianyu are made of stone and brick, but remote parts use rammed earth. The wall is not a continuous line; it has branches and natural obstacles like rivers and mountains. Despite popular belief, it is not visible from space with the naked eye. Construction involved soldiers, peasants, and prisoners, and hundreds of thousands are estimated to have died. Today, the wall attracts millions of tourists annually but faces conservation challenges from erosion and unregulated tourism.
