Il restauro della Batteria di Capo d’Orso a Palau (SS) in Sardegna: minimo intervento, reversibilità e autenticità

The military complex of “Capo d’Orso” in Sardinia is set in a very importance coastal landscape. It is an example of valuable military architecture, which documents important national and international war strategies. The Battery was built at the end of the XIX century; it was never used during the various wars, but, in particular between the First and Second World Wars, it suffered of considerable modernization interventions. Starting from a general overview of the military architectural heritage of the 'La Maddalena Archipelago – Palau' area, this article examines how protection has been implemented in this architectural heritage, showing how every intervention, even minimal, on these architectures that have been abandoned for decades, strongly affects from the architectural to the landscape scale. These are architectures that need of particular attention for the correct identification of design solutions for "reuse", so that the fundamental principles such as restoration are simultaneously understood, i.e. those of minimum intervention, compatibility, reversibility and authenticity, are achieved. In this paper we will try to understand how restoration can preserve the peculiar characteristics of historic military architectures, for example the inaccessibility and minimal visibility of the built environment in the environmental context, etc., where is difficult to resist at the current pressures of tourist use, in the marine context.
