The Garden of the Acqua Alta is tethered to the Arsenale Vecchio between the Arsenale to the west and Castello to the east, between the scales of imperial industry and those of the lived city. Positioned within the highest flood risk within a city built on slender wooden poles, the project invites Venice to reflect on its own fragility. In service of the perpetual remaking and restoration of the city and its images, the architectural proposition is at once a Garden with Pavilions and a Workshop with Yards. Built on hard edges, Venice loses the sense of the marshes on which it was built. The Garden aims to respond to Venice’s liquifying character by putting forward a series of heterotopias that occasionally seep westwards through the medieval wall of the Arsenale Vecchio and get caught in the urban fabric of Castello. The project echoes Venetian technological and environmental practices and proposes a social infiltration of the lived Venice at the West of the wall by means of restoring fragments of the city.
