This master’s thesis explores the complex legacy of architecture constructed during Mussolini’s regime and its subsequent treatment in post-war Italy. Using the EUR district (Esposizione Universale Roma) in Rome as a primary case study, Nebolsina investigates how post-fascist society has interpreted, utilized, and managed these ideologically charged urban spaces. The research is conducted through the lens of Critical Heritage Studies, a multidisciplinary framework that examines how cultural legacy is mobilized to define national identity and navigate power relations. The study traces the history of the EUR from its origins as a "Third Rome" meant to symbolize fascist continuity with the Roman Empire to its post-war survival. A key finding is that the management of this heritage was shaped by a tension between ideological "defascistization" and economic pragmatism. While some symbols were altered or removed—such as the renaming of monuments and the modification of statues—much of the infrastructure was preserved due to the country’s devastated post-war economy and the practical need for housing and office space. Ultimately, the thesis argues that the perception of fascist architecture remains fluid, influenced by aesthetics, personal memory, and shifting political climates. Nebolsina highlights that while many structures are now celebrated as modernist masterpieces or cultural heritage sites, the current rise of far-right politics in Italy risks re-activating their original ideological narratives. The work concludes that the management of such "difficult heritage" is a continuous process of negotiation between transformation and continuity
