The lagoon is an eco-system under constant transformation due to human intervention, and a space of relations which unites the terra firma, the internal archipelago and the offshore bars with the sea. The networks of existing museums could be hang together and get structured within the eco-museum, and be distributed along a new system of water transports. Insofar, our project initiates a long journey which will convolve the multiple local and cultural institutions, which will potentially become actors of the eco-museum of the Laguna. Two firmly rooted institutions have involved themselves in the realization of the project touching the lagoon of Venice : the Province of Venice (Department of Tourism and Communitarian Policies) which is the local entity including the lagoon in its jurisdiction, and the Giorgio Cini Foundation (Institute “Venice and Europe”), an international institution of a high cultural level located in the isle of San Giorgio. Both institutions have already launched projects in neighboring fields, such as, on one hand, the lagoon network of territorial museums and researches on the historical system of fortifications and, on the other hand, the Linguistic Atlas of the Mediterranean.
