The Great Wall of China is the longest building on earth. It winds through the hills and mountains of northern China. The Great Wall is so large that it can be seen from space! In places the wall is up to 25 feet tall. It is between 15 and 30 feet wide. The wall stretches for over 1500 miles.

Building began on the Great Wall more than 2,000 years ago. At that time, the Chinese people had enemies in the north. These enemies were forcing their way into China. The Chinese leader ordered workers to build the wall. He thought it would protect their land. The wall included towers and forts. At one time, over one million soldiers protected the wall.
Most of that first wall has crumbled away. The wall that remains was built between 1368 and 1644. Then building stopped. Today, workers simply repair it. They want to keep the wall in good condition for the Chinese people. People come from all over the world to see the Great Wall. Isn't it interesting that a wall built to keep people out now draws thousands to China every year?
