Abstract
At the turn of the Twentieth and Twenty-First century, many restoration interventions interpret the theme of the addition – or the filling of the lacuna – not only as an answer to the conservation needs of the building, but also as a design opportunity in which metal structures become an instrument of the architectural syntax. The use of building materials such as steel, Cor-Ten or titanium allows the development of additions/integrations that arise on the historical building as new stratigraphic layers, helping to realize a syntactic and formal distinguishability from the past. Intervention practices based on the use of metal devices are clearly consistent with the statement taken from the Krakow Charter (2000): «If necessary, for a proper use of the building, completion of more extensive spatial and functional parts should reflect contemporary architecture». These elements/structures aspire to the maximum reversibility of the intervention, also helping to minimize the extension of the anchor points between old-structures and new integrations. The paper analyses 5 interventions carried out on fortified buildings located in Italian territory between Trentino-Alto Adige region and Veneto region: the Juval castle (1997), the Tirol castel (2003), the Fürstenburg castel (1996-1999), the Firmian castel (2001-2006) and the scaliger castle in Ponti sul Mincio (2013-2015). The contribution will highlight that the interventions carried out in historic sites by these techniques show clear formal similarities. However, the outcomes of the interventions will be considered in terms of the inner coherence of the design choices, with particular attention in defining the construction details. In fact, the analysis of the working plan of each intervention – especially focused on the anchorage techniques used to connect the new insertions with the historical masonries – allows to underline significant mutual differences in the conservation of built heritage.
