The Venetian Lagoon, declared by UNESCO World Heritage Sire in addition to the city of Venice, is connected to the Adriatic Sea by three inlets: Lido San Nicolò, Malamocco and Chioggia. In a constant state of limbo between land and water, the lagoon is an ecosystem where continually changing environments coexist in the space between the mainland and the sea. "Element opposes element". This is how Bernardo Trevisan described the lagoon in 1718, as an environment subject to the actions of different forces, natural or man-made, which oppose one another. In addition to Venice, artistic and cultural treasure of inestimable value, do not miss to visit the isle of Burano, famous for its lacework, and Murano, famous all over the world for its glass making.
