MOSE (Modulo Sperimentale Elettromeccanico) is a large-scale engineering project designed to protect Venice, Italy, from flooding caused by high tides and storm surges. The system consists of a series of mobile barriers installed at the inlets of the Venetian Lagoon. When high water is forecasted, the barriers are raised to temporarily isolate the lagoon from the Adriatic Sea, preventing floodwaters from entering the city. MOSE aims to safeguard Venice's historic structures, residents, and economy from increasingly frequent and severe flooding events, a problem exacerbated by climate change and subsidence. The project is a key element in Venice's broader flood defense strategy.
