Why was the flood of 1966 especially important for Venice?

The flood of 1966 was a pivotal event for Venice because it served as a severe wake-up call regarding the city's vulnerability to environmental destruction. The disaster caused extensive damage to the city’s historic buildings and priceless art treasures, highlighting the urgent need for intervention against the combined threats of flooding, subsidence, and air pollution.123

This catastrophe prompted significant national and international efforts to rescue the city. Notably, UNESCO began coordinating a major international campaign to preserve Venice, leading to the establishment of various national committees dedicated to saving its heritage. Furthermore, the 1966 inundation stimulated long-term discussions and planning for structural flood-control projects, such as the mechanical barrage system designed to protect the lagoon. Despite these efforts, the city remains at risk, as administrative challenges and conflicting interests have historically hampered the implementation of comprehensive solutions.123
