Strumenti e metodi di ricerca in storia dell’architettura: l’indagine sul concorso internazionale di idee del 1969 per l’attraversamento dello Stretto di Messina

The contribution focuses on the research approach adopted within the doctoral thesis on the international ideas competition for the Messina Strait crossing project (1969), defended in 2023 at the Department of History, Representation and Restoration of Architecture (University of Rome La Sapienza). The aim is to bring out the premises of the research work and the criticalities sometimes encountered, especially in retrieving sources. The results highlight the richness of the competition’s legacy: the 154 proposals presented on that occasion confirm the multifaceted nature of the theme and demonstrate how the event was an important moment of confrontation on the most heated themes of the coeval debate on architecture and town planning.
