3The Great Wall of China
The Great Wall of China is an extraordinary feat of ancient engineering and one of the most recognizable structures in the world. Stretching over 13,000 miles (21,196 kilometers), this massive wall was built to protect Chinese states from invasions by nomadic tribes from the north. The Great Wall winds through rugged mountains, deserts, and plains, offering stunning views of the surrounding landscapes. The beauty of the Great Wall lies not only in its scale but also in the way it integrates with the natural environment, creating a sense of harmony between human achievement and the landscape.
