A conservação do patrimônio urbano encontra, nesta tese, aspectos de sua gênese legal na Itália. Abordam-se, em diálogo com a historiografia dedicada à obra de Gustavo Giovanonni, as importantes contribuições desse influente engenheiro para a introdução do conceito de \"ambiente\" nas leis de proteção do patrimônio cultural desse país no período entreguerras, inclusive aquelas voltadas para as chamadas \"belezas naturais e panorâmicas\". Com a interpretação de ideias e expressões utilizadas por Giovannoni, como \"ambiente do monumento\", \"ambiente tradicional dos lugares\" e \"complexo de coisas imóveis que compõem um característico aspecto com valor estético e tradicional\", evidencia-se ter sido ele um agente central à ampliação da tutela no seu país, para além daquela voltada ao \"monumento\" isolado, assim como para a introdução, na legislação, de instrumentos importantes para o campo da conservação urbana, como a figura do \"plano\". Nesse processo, identifica-se grande coerência entre a atuação do Giovannoni consultor ministerial e a do Giovannoni idealizador de leis, assim como entre o Giovannoni prático e o teórico, em campos imbricados como aqueles que hoje seriam definidos como do desenho urbano, do planejamento urbano e da conservação urbana. Intenta-se empreender uma abordagem historiográfica que contemple esse personagem, respeitando a complexidade de sua atuação. / The conservation of urban heritage finds, in this thesis, aspects of its legal genesis in Italy. Through dialogue with the historiography dedicated to the work of Gustavo Giovanonni, the thesis touches on the important contributions this influential engineer had on the introduction of the idea of \"ambiente\" in laws protecting cultural heritage in the country in the period between the first and second world wars, including those concerning so-called \"natural and panoramic beauties\". Through the interpretation of ideas and expressions used by Giovannoni, such as \"ambiente of monuments\", \"traditional ambiente of sites\" and \"the complex of immovable objects which form an appearance of aesthetic and traditional value\", we can see clearly that he was a key figure in widening the scope of protection laws in his country, taking it beyond that concerning isolated monuments as well as introducing legislation concerning important measures to be used in the area of urban conservation such as a master plan. During this process we can identify a great coherence between the work of Giovannoni as ministerial consultant and that of Giovannoni creator of laws, as well as the practical and theoretic Giovannoni in overlapping areas, such as those today defined as urban design, urban planning and urban conservation. The intention of this work is to use a historiographical approach which contemplates this man whilst respecting the complexity of his work.

Cette thèse questionne l’apport de la conservation du patrimoine urbain à l’urbanisme. Il y est avancé que l’association entre la conservation du patrimoine urbain et l'urbanisme, dans leur cadre conceptuel actuel, plutôt que d’être le catalyseur du renouvellement de l’urbanisme, a perpétué une appréhension fragmentée et une atomisation de l'établissement, consacrant ainsi le paradigme fonctionnaliste, qui conditionne encore largement les pratiques urbanistiques contemporaines, au Québec notamment. En effet, bien que depuis les années 1960 la conservation du patrimoine soit présentée comme le fil rouge dans le redéploiement de la compétence d’édifier, plusieurs études soulignent les résultats mitigés de nombreuses expériences de conservation ainsi qu’une contribution limitée relativement à la formulation des projets urbains. Plus particulièrement, malgré la reconnaissance de l’intérêt de la patrimonialisation et de la fécondité potentielle de l’idée de patrimoine en général, l’urbanisme n’est pas parvenu à en définir les termes de la contribution, tant au plan conceptuel que processuel, en regard de sa propre projectualité. De ce fait, il ne réussit pas à affranchir la réflexion patrimoniale du registre de la conservation afin de se l’approprier véritablement. Cette thèse explique les causes de cette incapacité à partir d’une analyse des conditions de l’appropriation de la notion de patrimoine urbain mises de l’avant par l’approche giovannonienne. Celle-ci, fondamentalement urbanistique, propose une conception du patrimoine urbain qui s’émancipe du monument historique et du registre de la conservation. Indissociable d’une projectualité urbanistique, l’intérêt pour le patrimoine urbain de Giovannoni relève d’une reconnaissance du déjà là qui fonde des modalités de prises en charge de l’existant. Celles-ci posent les bases d’un renouvellement de la manière de penser l’urbanisme. La notion giovannonienne de patrimoine urbain, qui réfère à l’ensemble urbain patrimonial, devient l’élément de base d’une analyse morphologique urbanistique qui permet de conceptualiser l’agglomération contemporaine comme ensemble marqué par les ruptures et les discontinuités. Prenant appui sur une démarche dialogique, l’approche giovannonienne relève d’une mise en tension des singularités et d’une appréhension conjointe des différentes registres, ceux des formes et des forces, de l’existant et du souhaité, du penser et du faire. Giovannoni dépasse ainsi l’opposition entre continuité et rupture portée par les pratiques afin de penser l’articulation du nouveau à l’ancien. La confrontation de l’approche giovannonienne aux différentes perspectives qui ont marqué l’urbanisme moderne, montre que ces modalités de prise en charge de l’existant sont conditionnelles à l’accomplissement des promesses de la considération du patrimoine urbain. Autrement, l’association de la conservation du patrimoine urbain et de l’urbanisme culmine dans une double assimilation : l’assimilation du patrimoine urbain au monument historique d’architecture conduit à confondre projet d’urbanisme et projet de conservation. / This thesis questions the contribution of heritage conservation to urbanism. It has been proposed that the association between heritage conservation and urbanism in their present conceptual framework, rather than being the catalyst for rethinking urban projects has perpetuated a sectoral approach and atomization of human settlement, thus entrenching the functionalist paradigm that still largely conditions contemporary planning practices, notably in Québec. Indeed, although heritage conservation has been a recurrent theme since the 1960s in the redeployment of town planning skills, several studies have underscored the mitigated results of numerous conservation attempts and also of the limited contribution made to the planning of urban projects. More specifically, in spite of the interest in heritage conservation and the potentially fertile nature of the idea of heritage generally, urbanism has not yet defined the terms of the contribution, not only from a conceptual point of view but also from a urbanistic point of view with respect to its project-based thinking (progettualità). Consequently, urbanism does not succeed in overcoming the heritage idea of the preservation register in order to fully encompass it. This thesis explains the causes of this inability from an analysis of the conditions for adopting the notion of urban heritage as advanced by Giovannoni. This fundamentally urbanistic approach puts forward a concept of urban heritage that has freed itself from the historical monument of the preservation register. Inseparable from an urbanistic project-based system, the interest for Giovannoni’s urban heritage arises from a recognition that what already exists creates a means for grasping the true personality of place and therefore offers insight for better urban design and planning. Giovannoni’s idea of urban heritage becomes the basic element of an urbanistic morphological analysis that allows for the conceptualization of the modern city as an entity marked by ruptures and discontinuities. Giovannoni exploits the differences in the personality of urban entities, such as places, neighbourhoods, etc., and visits back and forth between different scales and registers, those of forms and forces, of the existing and the hoped for, of ideas and action. Giovannoni thus goes beyond the divergence between continuity and rupture that marks, in a general way, the practices for envisioning the articulation of the new to the old. When we compare Giovannoni’s approach to the different views that have impacted modern urbanism, we find that his practices for using what already exists is the condition for the realization of urban heritage promises. Otherwise, the association of heritage conservation and urbanism culminates in the assimilation of urban heritage to the historical monument of architecture, and therefore leads to equating the urban project to the conservation project.
