The Great Wall of China

The Great Wall of China is a series of fortifications built to protect Chinese states from invasions. Construction began more than 2,000 years ago, with various dynasties, including the Ming, contributing to its length, which spans over 13,000 miles. Made primarily of stone, brick, and earth, the Wall showcases impressive engineering and served military, economic, and cultural purposes, facilitating trade while controlling migration. Today, it stands as a UNESCO World Heritage Site and an iconic symbol of China's history and resilience, attracting millions of visitors who marvel at its grandeur and historical significance.
