The coastal towers represent the Sardinian defence against piracy and Saracen incursions. Built from the 13th century onwards and continued until the first half of the 19th century, the whole defensive system was set up by the Spanish crown and maintained even in the Savoyard period until 1842 when the towers were abandoned. Usually located at strategic points for the defence of the territory, each tower was positioned in view of the previous and next tower to allow, in case of detection of enemy incursions, a rapid communication along the whole coast with special audiovisual signals. Today only some of them are restored and can be visited, thanks to the interventions of the Conservatoire du littoral; many others are in ruins and line the island landscape along the coast.
They are considered a symbol of the communities and the maritime identity of Sardinia.
