Construction of the Great Wall of China

The construction of the Great Wall of China began over 2,000 years ago, during the Qin Dynasty in the 3rd century BCE, and continued over many dynasties, lasting until the Ming Dynasty in the 17th century CE. Built as a defensive fortification against invading nomadic tribes from the north, the wall stretches over thousands of miles across China's northern border, incorporating various natural barriers like mountains and rivers. It was constructed using a combination of bricks, stones, and other materials, with watchtowers and beacon towers strategically placed along its length. The Great Wall of China stands as one of the most impressive architectural feats in human history and is a symbol of China's rich cultural heritage and enduring resilience.
