Venice’s Lagoon is an ephemeral natural element whose presence in our time is due to the direct action of human society
The defense of Venice from floods has not aimed to isolate the city from the sea, but rather to apply intelligent regulation to the natural tidal fluctuations, so as not to disrupt the lagoon's ecosystem services
The Venetian Lagoon is the result of centuries-long interaction between natural processes and human activity. Accurate scientific knowledge of natural dynamics forms the foundation for its sustainable management.
Today, the Venetian civitas is expressed through the interaction of nearly a million individuals, involving both lagoon settlements and mainland settlements within a single functional area
The urban form of Venice has evolved while preserving some original insights and achievements, which remain legible to this day
Venice as a technical and cultural system, the outcome of continuous collective invention, where architecture, engineering, and the environment are uniquely intertwined
The ongoing and developing projects led by a diverse range of public and private stakeholders operating in the city
Venice is the complex result of multiple intelligences
The exhibition narrates an extraordinary millennia-old project, a history of medieval inventions and contemporary technologies, interventions in nature and human settlement, and survival and resilience strategies through which the city has, for centuries, succeeded in thriving in a hostile environment, through the constant exercise of intelligence.
The installation covers an area of 500 square meters and is designed with a series of apses, vertical panels, and a central spine represented by a long table. It includes over 5,000 archive images, over 1,000 historical maps from the most authoritative databases, over three hours of video projections, and five interactive multimedia panels.
Five "Apses of intelligences" offer an immersive journey into the history and management of the lagoon and the city: "Millenary Time", "Regulated Lagoon", "Anthropized Nature", "Venice of the People", "Urban Form" will allow the public to explore the "intelligent" evolution of the city and its lagoon – which, for a long time, acted as its walls – along with the inventions and strategies developed for its use, and for the protection and enhancement of its cultural heritage.
The Venetian Abacus table, which extends 30 meters along the central axis of the Tesa, is dedicated to Ingenuities and represents the objects, tools, mechanisms, and technologies with which Venetians turned an uninhabitable place into one of the most important testimonies of global urban history. The "Actors of today and tomorrow" section animates the connecting walls between the Apses of Intelligences. It presents visions and projects of various public and private actors operating in the city.
Upon entering the Pavilion, visitors will find themselves immersed in a basilica-like architectural space, with a rhythmic wall structure created through a sequence of apses and vertical panels.
