Sighting and defense tower against Barbary corsairs
Following an incursion in July 1562 by the Barbary, coming from present-day North Africa, the community of the Prino valley obtained consent from Genoa for the construction of a defensive and sighting system consisting of a tower at San Lorenzo and one in Prarolo, both equipped with artillery.
The Torre di Prarola, built on the Premartello rock, housed six night watchmen with the task of signaling the dangers coming from the sea to the population.
The watchtowers were in visual contact with other high observation points along the coast and inland: in the event of an alarm, the information could travel simply through signals made with fire or smoke.
