Yesterday I posted a picture of the Great Wall at its eastern end, near Beijing. A few thousand miles to the west, the Great Wall ends (or begins) at JiaYuGuan, the last (or first) fortress along the Great Wall.
JiaYuGuan Fortress was built during the Ming Dynasty (14th Century) but is still well preserved. It then was the western-most fortress of the empire, and beyond it was desert. JiaYuGuan would see exiles exit its gates or merchants from the west enter after their journey along the Silk Road.
