Among the first structures to be built on the Calabrian shore is the Fort of Matiniti Superiore, known as Siacci. This is the most important Strait fortification in terms of size, architectural features and functions, together with its twin Fort Masotto on the Sicilian shore. This documentary tells the story of the social impact that Fort Siacci had on the territory, through the testimony of those who lived through it and those who, for various reasons, saw their lives linked to it.
