Over the next thirteen centuries, the seafaring city-state grew in power and strength. The art, architecture, and history amassed in the small “floating city” of Venice has earned it a place on the UNESCO list of World Heritage Sites. But the tide has turned, and the sea that once protected Venice now threatens it. Nestled in the Venetian Lagoon, the 118 low-lying islands of modern-day Venice are separated from the Adriatic Sea by a 45-kilometer (28-mile) chain of barrier islands. The Adriatic connects to the lagoon via three inlets—the Lido, Malamocco, and Chioggia. The sea now imperils Venice because of three conflated issues: groundwater pumping and offshore gas drilling have caused the city to subside; sea level has been rising; and natural tidal protections like mudflats and marshes have been disrupted over the past century. River courses have been made rigid, inlets have been widened, and the lagoon has been dredged to create shipping channels; adjustments to make boating and shipping safer have helped make the land more vulnerable. The city now regularly experiences Acqua Alta, or high water, when the tide inundates the streets and squares, menaces the historic architecture, and forces citizens to don galoshes. In 190
