Liquid Borders: The architectural and urban dialectic and identity of the Strait of Messina and the Bosporus

This presentation investigates the "dialectic of land and sea" as the primary driver of coastal urban identity. Using the Strait of Messina and the Bosphorus as comparative case studies, the research explores how the waterfront functions as a vessel for ancestral memory and a reference point for collective urban identity. These "border areas" are not merely geographic gaps but strategic, complex thresholds where architectural intervention directly reshapes political and cultural landscapes. The study employs a qualitative comparative methodology focused on: Historical Mapping: Tracing the artistic, mythological, and architectural layers of both straits to identify "stratigraphic" commonalities; Morphological Analysis: Examining the transition from "static" landscapes (the ferry-reliant culture of Messina) to "kinetic" ones (the bridge- connected continents of Istanbul); Case Study Synthesis: Analyzing the Messina Bridge Project as a contemporary disruptor of local identity against the established historical "bridge identity" of the Bosphorus; Observational Data: Intercepting current design trends that shift from "pursuing" a future to "accompanying" the existing cultural vibrations of the water. The research is grounded in the theory of Critical Regionalism, asserting that urban design in sensitive coastal areas must resist generic globalization. It provides a framework for architects and planners to treat waterfronts as "living archives" rather than blank slates. It advocates for "interception" over "imposition"—a design philosophy that prioritizes the acoustic, visual, and historical "bubbling" of the site. The originality of this work lies in its treatment of the Strait as an active architectural participant rather than a void. By placing the speculative future of the Messina Bridge. in direct dialogue with the lived reality of the Bosphorus, the study offers a unique perspective on how massive infrastructure can either amplify or silence the "ancestral memory" of a maritime border.
