Built this functional continuous great wall in my last China game. In runs the entire inner border of my empire in the homelands, and is flanked by 2 fort towns along either side of the mountains to the left, as well as a fort town in the center (just outside the wall chain) to prevent my aggressive neighbors from ever breaching the heart of the empire.
I was pretty much at war with my closest neighbors the entire game from the beginning of Antiquity, so the defensive line came in clutch!
