Il sistema difensivo costiero del Nord Sardegna: la Batteria Costiera Luigi Serra a Golfo Aranci

After the First World War, the development of offensive air power necessitated a thorough overhaul of Italy’s coastal defences. The new air threats forced the reconfiguration of existing anti-ship and anti-submarine installations, the adoption of concealment measures to make them less visible to enemy aircraft, and the construction of new fortified batteries designed for active defence based on sighting and response fire. The primary objective of anti-aircraft defence was to minimise the damage caused by enemy bombardment and to hinder enemy offensive operations. It was in this context that the so-called ‘second generation defences’ were born, including the Luigi Serra Battery, located at Punta Filasca in the municipality of Golfo Aranci, which is the subject of this work. The aim of the research is to document the state of a currently abandoned historical testimony and to propose some solutions for its future valorisation.
