ITA.CA, a visionary coastal defense and modular underwater habitat from Studio 3Mark, debuted at the 2025 Venice Biennale's 19th International Architecture Exhibition under the theme "TERRÆ AQUÆ. Italy and the Intelligence of the Sea". Framed as a simulated newspaper layout with authentic scale details, the initiative tackles ocean sustainability via architecture and tech advancements. It deploys nature-inspired, adaptable barriers from eco-materials to shield shorelines, boost sea life diversity, and revive ocean environments, aided by cutting-edge surveillance tools.
