Received: 1 April 2019; Accepted: 13 May 2019; Published: 16 May 2019 Abstract: The “Palazzo Ducale” museum complex in Mantua has been the object of intermittent interventions, which have not represented, over the last 30 years, a consistent strategy in terms of conservation. In the light of new financial and technological possibilities, a renewed management synergy has been activated: better operative decisions and the application of innovative tools are the core of this attitude. The article illustrates the path of knowledge activated in the museum’s “Cortile della Cavallerizza”: from archival research, geometrical survey and diagnostic analysis, up to the executive design of its conservative project. Keywords: historical analysis; conservation project; survey; BIM 1. Introduction The Palazzo Ducale complex of Mantua has been classified by d.m. 23/12/2014 (a ministerial decree regarding museums) amongst the autonomous national museums, which has been an important opportunity for taking care of the architectural complex. This has favoured a renewed process of management of its functions and of interventions in its built heritage. The interventions executed on the monument over the last 30 years have not followed a consistent conservation strategy. Direct observations of the complex and appraisals by the superintendents have shown how these operations were determined by the urgent needs of a particular time, and therefore were limited to occasional and partial actions. The availability of financial resources has activated a management synergy for new projects, supporting restoration activities research with the application of innovative technologies. This article aims to illustrate the knowledge acquisition process in the courtyard of the Cavallerizza, inside the museum complex, up to the executive design of the conservation project. 2. The Evolution of the Building Palazzo Ducale (Figure1) presents a varied historical and architectural stratification, strongly linked to the city life. The Gonzagas settled in Mantua from 1328 [1]. The Gonzaga [2] family promoted Renaissance culture through the contribution of important architects and painters who expressed their art within the Palazzo. With Ludovico II (1444–1478), Mantua became one of the most relevant centres of the Renaissance, giving hospitality to great artists Heritage 2019, 2, 1441–1459; doi:10.3390/heritage2020091 www.mdpi.com/journal/heritage Heritage 2019, 2 1442 Heritage 2019, 2 FOR PEER REVIEW 2 such as Leon Battista Alberti, Luca Fancelli and Andrea Mantegna.
