[Wonders of Civilization - Northern Border Wall] North side.
This Northern Border Wall, standing across the Strait Islands for a millennium, was ordered to be built by Hadrian, who canceled the Remit people's settlement, a ruler of legendary heroism, thus it's also called Hadrian's Wall.
From its completion to abandonment, it served as the northeast border of the Silver Empire.
The Northern Border Wall includes walls, watchtowers, inner fortresses, and castles, forming the wall system of the Ancient Silver Empire along with the Antonine Wall and Rheddian Border Wall.
Its primary purpose at the onset was to defend against the Three Great Barbarian Tribes to the north.
As for why it is now unused? And where did those Three Great Barbarian Tribes vanish to?
Now, those who established The Holy Silver Empire and ruled over this continent are the former barbarians.
