What is the Great Wall of China?
The Great Wall of China is an ancient series of walls and fortifications stretching across northern China. It's the longest wall in the world, extending over 13,000 miles (21,000 km)! Built over many centuries, its purpose was to protect Chinese states and empires from invasions.
Think of the Great Wall as a giant protective ribbon across China's landscape! It winds through mountains, deserts, grasslands, and plateaus. While it's famous as a single wall, it's actually many walls built during different dynasties that were later connected.
