About this subject

The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, and other materials, built over several centuries to protect Chinese states and empires from invasions. Contrary to popular belief, the wall is not a single continuous line but a collection of multiple sections constructed by different dynasties, especially the Ming (1368, 1644). The total length, including all branches, exceeds 13,000 miles (21,196 km), according to official 2012 surveys.

Construction began as early as the 7th century BC, but most of the remaining structure dates from the Ming dynasty. The most famous section, Badaling near Beijing, receives millions of tourists annually and is heavily restored. However, more remote sections like Jiankou offer a wilder experience favored by adventurers. The wall was designated a UNESCO World Heritage site in 1987 and is considered one of the New Seven Wonders of the World since 2007.

Beyond its defensive role, the wall served as a transportation and trade route, enabling customs control of goods along the Silk Road. Popular myths, such as the idea that it can be seen from space, are false, astronauts report it is barely distinguishable with the naked eye from low orbit. The structure faces conservation challenges due to natural erosion and unregulated tourism, prompting restoration efforts funded by the Chinese government and international organizations.
