innanzi tutto, un rigoroso approccio conoscitivo di natura storico-critica che, paradossalmente, si fa più arduo proprio nei confronti dell’edilizia storica di base, giacché sarà solo la conoscenza dei processi evolutivi della città ad essere in grado di svelare quei caratteri (distributivi, strutturali e linguistici) che, altrimenti, rimarrebbero sconosciuti (fig. 4). Non c’è chi non veda la distanza considerevole di un tale approccio rispetto a quello puramente ‘percettivo’ che domina l’attuale cultura architettonica. Ma dobbiamo pur sempre rispondere all’incessante domanda che viene sempre posta in questi frangenti: La nuova sistemazione del Mercato di Santa Caterina a Barcellona, Spagna, è una delle tante testimonianze di totale e gratuita prevaricazione dell’architettura contemporanea rispetto ad una preesistenza (fig. 5) The resettlement of Santa Caterina Market in Barcelona, Spain, is one of the many examples of free and total abuse of contemporary architecture with respect to a pre-existing (fig. 5) La risposta è che essa può giocare, con piena legittimità, un ruolo insostituibile nei processi ricostruttivi e reintegrativi, laddove venga messa al servizio della preesistenza enon già l’inverso, come è largamente dato osservare (Fig. 5). Ciò si lega, appunto, al tema della valutazione della ‘esigibilità’ del testo mutilo sul quale si interviene; più precisamente, si lega ai criteri che adotteremo per la reintegrazione delle lacune, sia architettoniche che urbane,prodotte dal sisma. Laddove queste possono essere risolte facendo ricorso al ricco patrimonio ideale e metodologico proprio della disciplina del restauro, il problema non deve essere minimamente può essere esclusa completamente l’architettura posto; ma laddove questo non fosse possibile, il contemporanea da tali processi ricostruttivi? linguaggio contemporaneo può assolvere il compito reintegrativo o allusivo degli spazi o delle masse murarie perdute. Non si tratta, in questi casi, di andare ‘oltre il restauro’, ma di rimanervi all’interno, nel pieno rispetto dei principî conservativi nei quali ci riconosciamo.

It is necessary, on the other hand, to acknowledge how the theme of reconstructing historic building heritage, whenever it is damaged to a greater or lesser degree, is typically architectural restoration, re-integrating lost parts of a significant monument for the community, or reconstructing part of the urban fabric. Let’s start, first of all, from a preliminary consideration that I believe to be fundamental: after a traumatic event, no building can really be considered 'lost’ as traces of it, even in the most serious cases, will always remain. It follows that the total cancellation of a building, or an urban fabric, is always ‘intentional’ and we have evidence of this in history. If we accept this preamble, the prospect radically changes since the right attitude is not that of asking ourselves which architectural forms will compensate for the lost parts, which may be 'assonant' (resorting to falsifying copies, as much as to the so-called 'adapted modern' solution), or 'dissonant' (as can largely be seen in the current architectural scene); on the contrary, we must ask ourselves to what extent, and how, the damaged building is actually ‘in need’. Obviously the status of being ‘in need’ (which the supporters of the 'How it was and where it was' always consider possible) must be subject to a careful critical assessment and may vary based on the testimonial value of what was there before. Ultimately, we must ask ourselves on the one hand about how 'in need' the remaining parts of a specialist building also bearing artistic value are, and on the other hand about the recomposition of urban fabrics compromised by an earthquake. In both cases, the consequent design and operative issues must be approached from a restoration viewpoint, hence with exclusively conservative aims. All this implies, above all, a rigorous cognitive approach of a historical/artistic nature which, paradoxically, actually becomes more demanding in relation to basic historic building, inasmuch as it is only the knowledge of the processes of evolution of the city that can reveal the characteristics (distributional, structural and linguistic) which would otherwise remain unknown. There is no-one who doesn’t see the considerable distance of such an approach with respect to the purely 'perceptive’ one that dominates current architectural culture. But we still need to answer the incessant question that is always posed in these situations, i.e. can contemporary architecture be completely excluded from these reconstruction processes? The answer is that it can, legitimately, play a full and irreplaceable role in the reconstruction and re-integrative processes, where it is used to serve what was already there and not the opposite, as has often been observed. This is exactly connected with how much the damaged building is 'in need' of effective intervention; more precisely, it is connected with the criteria to be adopted for the reintegration of the gaps, both architectural and urban, caused by the earthquake. Where these can be easily resolved by resorting to the rich ideal and methodological heritage of the actual discipline of restoration, the problem need n
