In the country of China, there is a wall that is 1,500 miles long. It is called the Great Wall of China. It winds uphill and down, through valleys and mountains. Every inch of this 1,500- mile wall was made by hand. The Great Wall of China is made many, many years ago. The people of China made it to keep out their enemies. There are watch towers all along the way. The Wall is made of brick and earth. It is high and wide on top. People can walk along the top as if it were a road. It is said that it took ten years to build one part of this wall. No other defense line has ever been made as long as the Great Wall of China.
