The height and width of the Great Wall?

The average height of the Great Wall is 7.8 meters, the average width at the base is 6.5 meters, and the top is 5.8 meters.

The Great Wall, also known as the Great Wall, is an ancient Chinese military defense project.

The history of the construction of the Great Wall can be traced back to the Western Zhou Dynasty, and the famous allusion "playing with beacon fire on the princes" originated from this. During the Spring and Autumn Period and the Warring States Period, when various countries competed for hegemony and defended each other, the construction of the Great Wall entered its first climax, but at this time the length of the construction was relatively short. After the Qin Dynasty destroyed the six kingdoms and unified the world, Qin Shihuang connected and repaired the Great Wall during the Warring States Period, and it became known as the Great Wall. The Ming Dynasty was the last dynasty to overhaul the Great Wall. Most of the Great Wall that people see today was built at this time.

On March 4, 1961, the Great Wall was announced by the State Council as the first batch of national key cultural relics protection units. In December 1987, the Great Wall was listed as a World Cultural Heritage.
