Founded in the fifth century, Venice is built across around 100 islands linked by canals and more than 300 bridges. The city floods increasingly often, which has prompted concern from both politicians and scientists, who are keeping a close watch on this UNESCO World Heritage Site. To counter the rising waters, the city has embarked on a vast project entitled MOSE (Moses in Italian), which consists of a highly sophisticated structure of dykes to prevent flooding. How was such an engineering prowess made possible? What resources have been mobilized for this one-of-a-kind construction? Like a journey back in time, this documentary goes from the city’s foundations to the Venice we know today. Historians, architects, engineers and residents share their love for this unique city, which they are trying to save from the waters through an ambitious architectural project on an unprecedented scale.
