Here’s one of my favorite images from "Overview” - Venice, Italy. The city is situated upon 118 small islands that are separated by canals and linked by bridges. With its tide waters expected to rise to perilous levels, the city has constructed 78 giant steel gates across the three inlets, through which water from the Adriatic could surge into Venice’s lagoon. The panels – which weigh 300 tonnes and are 92 feet (28 meters) wide and 65 feet (20 meters) high – are fixed to massive concrete bases dug into the seabed.
