Venice is at risk of sinking due to a combination of factors: foundations not reaching solid bedrock, rising sea levels, and the weight of buildings and people.

The city is currently sinking by 1 to 2mm per year, and experts warn it could be underwater by 2100 without intervention.

The MOSE project, designed to install barriers to prevent flooding, has experienced delays and cost overruns.

Alternative solutions, such as pumping concrete into the ground to stabilize foundations, present their own challenges.

Venice's historic buildings and cultural heritage are in jeopardy unless effective measures are implemented to address the sinking issue.
