The Great Wall that still stands today is much grander than Shi Huangdi’s wall.
The Ming dynasty started building the wall that still exists. That was in 1368 CE. Much of the Great Wall is 25 feet high and just as wide. Made mostly of brick and stone, it has tall watchtowers. The Ming dynasty built many sections and branches. They cover more than 5,500 miles. Natural barriers, such as rivers and hills, cover about a quarter of that distance. A small part of the wall is made up of ditches. In 2012, the wall was measured. The report said its total length, including parts built at many different times, is 13,170 miles.
