The Great Wall was built in sections over many centuries by different ruling dynasties.

The longer version

Long defensive lines rarely appear all at once, and this one is no exception. Different states built earth ramparts along their own borders, and later rulers joined, rebuilt or abandoned those stretches according to where raids came from and how far their armies could be supplied.

The material followed the land: stamped earth in the plains, stone and brick near passes, watchtowers on ridges. Signal towers passed smoke or fire by day and night, and garrisons farmed nearby to feed themselves. What survives today is therefore a patchwork of many building campaigns rather than a single project.
