The Great Wall of China spans approximately 13,170 miles (21,196 kilometers) in total length, including its various branches and sections built over different dynasties. The wall varies in height and width, with some parts reaching up to 30 feet (9 meters) high and 15 to 30 feet (4.5 to 9 meters) wide. Its construction began as early as the 7th century BC, and it primarily served as a defense mechanism against invasions.
