Florence, World War II. July 1944.

The city, occupied by Nazis for the past year, is on the brink of liberation by Allied forces. 

“The Allied forces are advancing on Florence,” confirmed the thousands of leaflets that fluttered from the sky, dropped by American planes. “The city’s liberation is at hand. Citizens of Florence, you must unite to preserve your city and to defeat our common enemies…Prevent the enemy from detonating mines which they may have placed under bridges…” ¹

But different directives were coming from the German high command to the cittadini of Florence. On July 29, 1944, residents along the Arno river, which flows directly through the city, were on alert. The approximate 100,000 people who lived near the waterway and its bridges were warned to vacate their homes by noon the next day. Taking furniture and personal belongings, it was specified, would not be necessary. Some took refuge in nearby Pitti Palace, a former Medici mansion. The entire Arno area was soon blockaded, and guarded under the watchful eyes of German paratroopers. 

On August 3, a more ominous warning came from German high command:  “Beginning from this moment, it is prohibited for anyone to leave their homes and walk in the streets or piazzas of the City of Florence. All the windows, even those in cellars, together with the entrance and hallways of houses, shall remain closed day and night. The population is advised to stay in their cellars, and where they do not have one, to go to a church or other big building. The patrols of the German armed forces have been ordered to shoot at anyone who is found on the street or who appears at the windows.” ²

Could the Florentines have known what was to come? 

Later that night, one by one, Florence began losing its historic bridges. By the next morning, five out of the six bridges spanning the Arno were reduced to rubble, blown up by retreating German forces to make it difficult for Allied forces — who would arrive at the city’s Porta Romana later that day — to reach the city center.

Ponte alla Carraia. Ponte alle Grazie. Ponte San Niccolò. The order in which they fell may be lost to history, but record shows that the graceful and elegant Ponte Santa Trinità– completed in 1569 from design input thought to be from Michelangelo — fell around four o’clock on the morning of August 4th,  but not without a fight. Three rounds of explosives were needed to ultimately destroy it. “The sun would rise moments later, but [Ponte Santa Trinità] would never again cast the same shadow on the Arno.” (3) 

Of the lost bridges, three stood where bridges had been since the 13th century: Ponte Santa Trinità, Ponte alla Carraia and Ponte alle Grazie. The remaining bridge: the irreplaceable Ponte Vecchio. Florence’s oldest bridge, the bridge we see today is the one which has stood since 1345. Stories vary on why the Ponte Vecchio was spared while the other ponti were not. 

One is that the bridge was saved by a last-minute order from the German officer in command. Another is that Operation Feuerzauber — the name for the bridge destruction operation — called for the destruction of all bridges except the Ponte Vecchio. A recently discovered letter, however, suggests instead “that a brave shop assistant may have disabled the mines placed on the Ponte Vecchio, preventing its destruction.” (4) 

Whatever it was that saved the Ponte Vecchio, demolished in its place were adjacent historic buildings and streets, leaving enough devastation and rubble to render the bridge useless as a connector to the other side of the city for liberating forces.

It must have been an overwhelming mix of emotions for Florentines to reconcile when morning dawned: survival and liberation, but also, extreme loss.

Historian Christopher Hibbert retells the story of one particularly poignant exchange. One of Florence’s art historians had taken refuge at Pitti Palace with his family, just a five-minute walk from the Ponte Vecchio:

 In the early light i looked from a window overlooking the Piazza…i opened the window and called out, ‘Where are the Germans?’

‘There are none here any more. They are all across the Arno.’

‘And the bridges?’

‘All blown up, except Ponte Vecchio.’

“Viva l’Italia!” cried one of the partisans. 

“Viva l’Italia!” I called back, but Italy no longer had the Ponte Santa Trinita… ¹

But Florence, cradle of the Renaissance, is no stranger to rebirth. In time, new life was yet to come for the bridges of the Arno. Through painstaking work, the bridges of Florence slowly reappeared. 

Just two years after liberation, Ponte alla Vittoria was opened, and Ponte San Niccolò followed in 1949. Then came Ponte alla Carraia in 1951 and Ponte alle Grazie in 1953. Finally, in 1958 came the beloved Ponte Santa Trinità, painstakingly reconstructed with stones from the original structure retrieved from the Arno and materials from the quarry which had provided material for the original bridge. In an effort to maintain authenticity, replicas of sixteenth-century tools were custom made and used in the construction. 

Today, Ponte Santa Trinità (above) is a breathtaking beauty, likely a main character in countless photos of the 11 million visitors who flock to Florence every year. Visitors who stand along the Ponte Vecchio, surrounded on all sides by the city of the Renaissance, six bridges once again spanning the Arno in the heart of Florence’s historic district. 

Rebirth, indeed.

Additional Bridge History

Ponte Santa Trinita (Holy Trinity Bridge), a Renaissance-era bridge just to the west of Ponte Vecchio, has been called the most beautiful bridge in the world, and is the world’s oldest elliptical arch bridge. Ponte Santa Trinità had a tumultuous early history, having been swept away by flooding waters from the Arno three separate times (1252, 1333 and 1557). It was after the 1557 flood that Giorgio Vasari was asked to oversee its reconstruction, who in turn consulted Michelangelo (the graceful arches seem to be attributed to him). Ultimately it was architect and sculptor Bartolomeo Ammannati who oversaw the bridge’s construction, completed in 1569.

To the west of Trinità is Ponte alla Carraia, named for the carts (carri) which passed through the gates. It started as a wooden bridge in 1218, but also had a history of loss — floods in 1274 and 1333, collapse under a crowd in 1304. Updated and remodeled in 1867 by Bartolomeo Ammannati under the request of Grand Duke Cosimo I de’ Medici. 

Ponte Vecchio’s neighbor to the east is Ponte alle Grazie, which began its life in the early 1200s and was known then as Ponte di Rubaconte, named for the man who commissioned construction. Prior to its destruction in 1944, the bridge underwent a variety of changes, including a new name, sharing the name of the chapel which was then located on the bridge.
