Spigolature in alcuni interventi su preesistenze nei disegni di architettura (1890-1930)

Roughness in some works on existing buildings in architectural drawings (1890-1930) The paper offers the opportunity to know more about conservation and restoration as disciplines in Italy between 1890-1930, a particular peri od, thanks to the documentation conserved at Centro di Studi per la Storia dell’Architettura. It was a rediscovering of historic values in AACAR. Two different theories were recognized in the archival documentation, thus two kinds of projects: one can be intended as the end of “stylistic restoration”, another one is the so-called “scientific restoration”. The research allowed at pointing out the work carried out by AACAR as forerun ner, including the various manner of operating on existing buildings in Italy. The various projects show the restoration faithful to the philologic/ scientific theory, as in the long period leaded by Camillo Boito, Gustavo Giovannoni, Antonio Muñoz, and the restoration faithful to the stylistic theory, aimed at completing unfinished or damaged architectures. Illustrating some examples, the paper highlights unknow reconstruction pro jects, as those regarding the cathedral of Cagliari San Francesco al Prato, and the church of Sant’Agata in Perugia, as well as different phases of the Cathedral of Orvieto and Santa Maria Maggiore in Città di Castello. Regarding the cathedral of Pienza, the works on the foundations and on the walls can be considered as a reinforcement and restoration project, as those on the Cathedral of Cremona and on the Cathedral of Fermo
