El Torreón marks the start of Vernazzo's ancient defensive walls, a medieval tower of genuine historical significance. This well-preserved remnant of the Genoese fortification system once protected the village from maritime raids. Standing at the entrance to the old walls, the tower offers insight into the military architecture that shaped the Cinque Terre settlement. A modest but compelling piece of the town's medieval heritage, worth visiting to understand Vernazzo's strategic position on the Ligurian coast.
