Mean when the name was give the great wall of china which year and who?
Construction of the Great Wall becan in the 7th Century BC, and was completed during the Ming Dynasty (1368 - 1644). It's length is 5,660 km.
The wall is located in Northern china and starts from Shanhai Pass in the east, to Jiayu Pass in the west by way of Hebei, Beijing, Shanxi, Inner Mongolia, Ningxia, Shaanxi and Gansu.
This information was extracted from a Chinese book called The Great Wall.
No one discovered it. It was built.
First, what we know as the Great Wall is not a single wall, and second, it was not built all in one stretch, so it is impossible to nail down an exact time of its construction or to name a single creator. It was built sporadically, in sections, as funds of politics allowed, from 620 BC up through the 16th Century.
