The Florence Flood of 1966

A historical reference on the flood of November 4, 1966 - and the world's effort to save Florence.

On the morning of November 4, 1966, the Arno overran its banks and flooded the center of Florence under water, mud and heating oil - up to 6.7 meters (22 feet) deep in places. Thirty-five people died. Thousands of works of art and close to a million books at the National Library alone were damaged, and young volunteers came from around the world to dig the city out. The rescue that followed changed the way the world cares for its art and books.

This site has documented the flood and its legacy since 2006, and helped bring some of the rare color photographs of the flood itself to the city archive of Florence.

After some on and off digging around, I finally tracked it down as the work of architectural photographer Balthazar Korab (more on that side of the story soon).
