Where is the Italian Great Wall?

It is located in the Fort of Fenestrelle, in the Val Chisone valley. The complex includes 3 forts and 7 redoubts connected by a wall that closely resembles the Chinese Great Wall. The wall stretches about 3 kilometers, linking various fortifications along the mountainside. In some parts, the wall reaches a height of 10–15 meters. Inside the wall runs a staircase that was used to transport ammunition and soldiers.
