High Risk

Venice and its Lagoon

Italy • Cultural Heritage • Threatened by flooding and climate change

History and Importance

Venice is one of the world’s most famous historic cities and is known for its canals, bridges, architecture, and cultural history. Built across more than 100 small islands in a lagoon along the Adriatic Sea, Venice became a powerful center of trade and art during the Middle Ages and Renaissance.

The city contains historic churches, palaces, public squares, and waterways that attract millions of visitors every year. Venice’s unique design and cultural importance have made it one of the most recognizable heritage sites in the world.

Current Threats

Venice faces increasing flooding caused by rising sea levels and climate change. Seasonal flooding events known as “Acqua Alta” have become more frequent and severe in recent years.

Heavy tourism also places pressure on the city’s infrastructure, historic buildings, and local communities. Large cruise ships, overcrowding, and environmental damage continue to threaten the long-term stability of Venice and its lagoon.

Preservation Efforts

Preservation projects in Venice focus on flood protection, restoration of historic buildings, and reducing environmental damage.

Large engineering systems such as the MOSE flood barrier were built to help protect the city from rising tides, while conservation groups continue working to preserve Venice’s cultural and architectural identity.
