Why was Venice built on stilts?

Venice was built on stilts primarily due to its unique geographical setting in a lagoon, where the ground is primarily marshland and prone to flooding. The use of stilts, made from sturdy wood, allowed for the construction of buildings above the water level, providing stability and protection from rising tides. This architectural approach also helped prevent damage from moisture and flooding, which are common challenges in the region. The lagoon's natural barriers further contributed to the city's defensive position against invasions.
