Placed at the main axis of the island, these structures once marked the invisible border between life and death. After more than half a century, many are still there, immersed in the Sicilian landscape, like the remains of an ancient civilization that slowly disappears.

Gradually, these structures are fading away, destroyed by weather or by handman. Observation points that have lost their function, blinded Cyclops who can no longer see or hit and waiting for the moment when there will no longer be any trace of them.
