On November 4, 1966, Florence experienced one of the worst floods in its history. After days of heavy rainfall, the Arno River overflowed, which sent water, mud, and debris through the city's streets. Homes, businesses, churches, and museums were flooded, and thousands of valuable works of art and historical documents were damaged.
Now, 60 years later, Florence is remembering the flood and the people who helped the city recover. Although much of the damage has been repaired, the events of November 4, 1966, remain an important part of Florence's history.
In the days leading up to November 4, heavy rain fell across Tuscany, causing the Arno River to rise rapidly. During the night of November 3 and the early hours of November 4, the river overflowed its banks and flooded much of Florence's historic center.
Water rushed through the streets, carrying mud, debris, and fuel oil into homes, shops, churches, and museums. Some of the worst flooding occurred in the Santa Croce neighborhood, where water reached nearly five meters in certain areas.
Many residents were forced to take shelter on upper floors and rooftops as the water continued to rise. When the floodwaters finally receded, the streets were left covered in thick mud, and much of the city faced a difficult cleanup.
The flood caused widespread destruction, claimed lives, and damaged thousands of buildings and works of art.
Florence is known around the world for its Renaissance art and architecture, and the flood put much of this history at risk.
Museums, churches, libraries, and archives throughout the city were flooded, damaging paintings, sculptures, books, and historical documents. Many of these objects were hundreds of years old and required extensive restoration.
One of the most famous examples was Cimabue's 13th-century crucifix, which was kept in the Basilica of Santa Croce. The painting was severely damaged by the flood, losing approximately 60% of its painted surface. It became one of the most well-known symbols of the disaster.
The Uffizi Galleries were also threatened by the rising water. Museum staff worked to protect the collections, moving artworks to safer areas wherever possible.
The damage went far beyond what could be seen in the streets. For years afterward, restoration experts worked to save Florence's artwork and historical collections, some of which are still being studied and restored today.
After the flood, thousands of volunteers came to Florence from across Italy and around the world to help with the cleanup.
They became known as the Angeli del Fango, or Mud Angels.
Many of these volunteers were young students who spent their days clearing mud from buildings, helping residents, and rescuing damaged artwork, books, and documents.
Their work was especially important in Florence's libraries, where thousands of books and manuscripts had been soaked in muddy water. Volunteers helped remove the damaged materials so restoration experts could begin the process of saving them.
The Mud Angels played an important role in Florence's recovery and are still remembered today for their generosity and willingness to help a city in need.
Cleaning up the streets and repairing damaged buildings was only the beginning of Florence's recovery. Restoring the city's artwork and historical collections would take much longer.
The flood brought international attention to the importance of art conservation and led to improvements in restoration techniques. Specialists from around the world worked together to find ways to save paintings, sculptures, and documents that had been damaged by water and mud.
Florence's Opificio delle Pietre Dure, one of Italy's leading restoration institutions, was heavily involved in these efforts.
Some projects took decades to complete. For example, Giorgio Vasari's Last Supper, which was badly damaged during the flood, underwent years of restoration before returning to public display in 2016, fifty years after the disaster.
The work that followed the flood helped shape many of the conservation methods still used to protect artwork today.
November 4, 2026, marks 60 years since the Great Flood of Florence. The anniversary is an opportunity to remember what happened, recognize the people who helped the city recover, and reflect on the importance of preserving Florence's history.
Throughout the city, commemorative events and exhibitions are bringing attention to the flood and its lasting impact.
Even today, visitors can find reminders of what happened in 1966. In several parts of Florence, plaques on buildings mark the height the floodwaters reached.
The Santa Croce neighborhood is one of the most significant places connected to the disaster. Walking through the area today, it can be difficult to imagine the streets filled with several meters of muddy water.
These small reminders offer a glimpse into a part of Florence's history that visitors might otherwise overlook.
Today, Florence continues to welcome millions of visitors who come to experience its art, architecture, and history. Many of the churches, museums, and landmarks that were damaged in 1966 have since been restored.
The flood remains an important reminder of the work that goes into protecting these places and the people who have helped preserve them over the years.
