Abstract: This work is part of research conducted within the Di3A Landscape Design and Redevelopment Laboratory at the University of Catania. Its objective is to improve the enjoyment of public spaces through the study of landscape design in highly urbanised and historical areas. The case study used was the historical centre of the city of Catania in Sicily. This study focused on the green aspects of the redevelopment of some open spaces of the Antico Corso district using international and national thematic studies on public spaces as a reference. In particular, the research concentrated on the design of the Garden of Via Biblioteca inside the former Benedictine Monastery of San Nicolò La Rena, a UNESCO world heritage site redeveloped by the famous architect Giancarlo De Carlo. After a careful analysis of the area, we decided to use contemporary project themes with the aim of enhancing the present historical elements and nature-based solutions, which, through the introduction of carefully selected plant species, favour biodiversity in the urban environment. The method adopted was divided into three main phases: (1) spatial analysis; (2) a SWOT analysis method; and (3) the planning and design of the green redevelopment of places to be reconverted into public spaces. This methodology has already been tested on the open spaces of the former Vittorio Emanuele Hospital inside the Antico Corso District, showing how the multidisciplinary approach applied can be replicated in other urban contexts in historical centres. The results of these studies may be useful in the context of urban planning reforms envisaged by Regional Law No. 19/2020 and Regional Law 13/2015 in Sicily and to help the Superintendencies of Landscape and Cultural Heritage to preserve and to enhance historical greenery. The adopted strategies may also be useful in the application of the PUI (Integrated Urban Plan) of the Province of Catania that follows the PNRR (National Plan of Reconstruction and Resilience) parameters to provide local services to the municipalities involved. These pilot projects should be extended to bigger areas. The applicability of the methodology could be tested in other parts of the Municipality of Catania with a particular focus on run-down areas, followed by further testing on territorial sections of the province.
