History of the Great Wall
The Great Wall of China was constructed over a period of several centuries, beginning in the 7th century BC. The first walls were built by individual states to protect their territories from each other. Over time, these walls were connected and extended to form the Great Wall we know today.
The Great Wall was built and rebuilt many times over the centuries. The most significant construction was during the Ming Dynasty in the 14th century. The Ming Dynasty built the most well-known sections of the Great Wall, which are still standing today.
