We could so punctually recognize medieval urban tissue like inadjacent parts, the rectifications of alignment and the sixteenth-century aggregations, the monumental replanningof some eighteenth-century façades; and also the earthquakes and war events damages, thenineteenth-century completions and interventions with hygiene and decorum intents, especially after theUnity of Italy, when Palermo had to appear like the other cities of the new State. All this conditions had tocoexist in a difficult city, where decorum of monumental architectures has been often subdued to comfortand to commerce demands, to the fragmentariness provoked by nobility decadence, to the aggressive anddisfigured installations.The study of architectural fronts analyzes about sixty civil buildings along the Vittorio Emanuele main street,and it’s initially founded on a cognitive process that includes historical analysis, geometric and dimensionalsurvey, analysis of material and decay systems. We particularly analyzed both the relationships amongdecay systems and historical stratifications, both the grammar of architectural façades language.In a second phase, this study includes a project proposal that, according to the individuality of cases, itwould assume the sense of an intervention code about some recurrent critical aspects on which it’s possibleto intervene only applying codified procedures. The proposed designs represent so an application toconcrete cases, not abdicating to involve physical and economic urban environment: as example we citethe complexity of those solutions that would respect the historical image of building without depressing thecommercial demands of ground floor shops.
