Resumen de Le strutture di difesa ad Alghero (Sardegna). Tra restauro e tutela
The construction of the first walls built in Alghero probably dates back to the 12th century, when the city was founded by the Genoese Doria family. In the thirteenth century, an important extension of the walls was carried out, during the Aragonese domination: there was the presence of 26 towers, square or polygonal towers, about three meters higher than the walls (6-7 meters high), of which today remains testimony of a part of this masonry incorporated in the sixteenth-century tower of Porta Terra. In the 16th century the defensive wall circuit was redefined again. In 1861 Alghero, as others city, was cancelled from the strongholds of Italy and, to ensure the expansion of the city, parts of the walls were demolished. Today the walls of the city of Alghero are preserved for about 1.3 km of total linear development, coinciding with about 70% of the historical wall circuit. It is interesting to observe the restorations made so far, the various activities aimed at enhancing the value that have taken place in these spaces, whether they are the towers or the open spaces adjacent to the wall circuit in particular, where parts of the walls have been demolished. In this paper there are analyse the different approaches to solve problems generated by historical fortified buildings transformations and walls partially demolitions. How is possible have a compatible use in these spaces and guarantee a conservation of cultural heritage? It is also interesting to make an assessment of the state of conservation and the current damage present in this architectural complex, in order to identify a future direction and investment needs in terms of various types of resources (human or monetary).
