Imagine a wall long 3 km, snaking down from the altitude of 1800 m above the surface, situated in natural park, where whenever you look you will see mountains and valleys, juicy green of trees and if you are lucky even a predator circling on the sky. It’s how the biggest in Europe fortification – Forte di Fenestrelle (the Fort of Fenestrelle) – looks like. It’s located in a small town Fenestrelle, 74 km from Turin.
