Venice is easiest to recognize in a photograph of canals and palaces, but the World Heritage property is much larger than the historic centre. “Venice and its Lagoon” includes the city and a broad coastal ecosystem in the Veneto region. UNESCO describes a landscape of 118 small islands, settlements and tidal wetlands shaped by both natural processes and centuries of human engineering. To understand why the city looks as it does, visitors need to see water not as a backdrop, but as the condition that shaped its streets, economy and vulnerabilities.
UNESCO dates the first settlements to the fifth century, when people sought refuge on lagoon islands amid upheaval on the mainland. Over time, temporary communities became permanent, and Venice developed into a major maritime power by the tenth century. The lagoon was not an empty barrier around the city. Its channels connected settlements and trade, while mudflats, marshes and islands formed a working environment for fishing, navigation and construction.
