About Great Wall of China
Not a single wall but a series of walls built over 2,000 years. The most well-known sections were built during the Ming Dynasty. Over 1 million workers died during its construction. Cannot be seen from space with the naked eye despite the popular myth. Stretches across 15 Chinese provinces. Built from stone, brick, tamped earth, and wood.
