The Great Wall Of China - The Timeless Guardian Of Ancient China Stock Photography

The Great Wall of China, a colossal structure stretching over 13,000 miles, is one of the most impressive and well-known feats of engineering in human history. Originally constructed over several dynasties, primarily the Ming Dynasty (1368–1644), the Great Wall served as a defense system against invasions from the north, particularly by the Mongols. This UNESCO World Heritage site is composed of walls, watchtowers, fortresses, and natural barriers, weaving through rugged mountains, deserts, and grasslands.
