Ponte Vecchio

The Arno's narrowest point in Florence carried a crossing long before the present bridge; soundings at the end of the 1950s found two wide concrete foundations, probably of the first Roman bridge. It was widened around 123 AD, when Hadrian promoted the via Cassia Nuova through the city, and is thought to have been lost in the sixth or seventh century to neglect, war and flooding.

A stone at the bridgehead marks, with Dante's lines from Paradiso, where the Amidei murdered Buondelmonte de' Buondelmonti in 1215, the killing that opened the city's Guelf and Ghibelline fighting. The bridge fell after the first Arno flood of which firm record survives (dated 1117 in some accounts, 1177 in others), and was rebuilt with five arches on older remains. Fires took it in 1222, 1322 and 1331. A flood on 4 November 1333 swept it away but for two central piers, as Giovanni Villani noted in his Nuova Cronica.

Reconstruction began around 1339 and closed in 1345, as two plaques set up then and still in place attest. The design is assigned three ways: Vasari credited Taddeo Gaddi, on the tradition of his day; Neri di Fioravante was capomastro of the Signoria in those years; fra' Domenico da Campi had lately rebuilt the Ponte alla Carraia. A weathered stone in the central loggia recorded the bridge's fall in the deluge of 1333 and its rebuilding ten years later, as it pleased the Commune.

Its three shallow segmental arches (a main span of 30 metres and two of 27) broke with the Roman semicircular model, held to be the first such departure in the West. Four crenellated blocks stood at the ends, around the central piazza that Leon Battista Alberti called an ornament of the city, and a tower watched each corner; only the Torre dei Mannelli, raised at the south-east corner to defend the crossing, still stands.

In 1442 the city assigned the bridge's shops to greengrocers and butchers, who could tip their waste into the river. In 1495 the Comune sold forty-eight shops to private owners and to lay and religious bodies, who enlarged them with overhangs over the water.

In 1565 Vasari built for Cosimo I the elevated corridor joining Palazzo Vecchio to the Medici residence at Palazzo Pitti: some 760 metres, put up in five months, running above the east-side shops. The butchers were turned out in favour of goldsmiths and jewellers, to keep an ignoble and foul-smelling trade from under the corridor's windows; the decree is dated 1565 in some accounts and 27 September 1594, under Ferdinando I, in others. The restriction still holds; the tenants are jewellers, art dealers and souvenir sellers.

The back shops overhanging the water date from the seventeenth century, the projecting displays called madielle from the eighteenth. In 1900 the bridge's leading goldsmiths commissioned the sculptor Raffaello Romanelli to make a bronze bust of Benvenuto Cellini for a fountain at its centre, on a base by Egisto Orlandini, unveiled in 1901 for the postponed fourth centenary of his birth. That same year the General Directorate of Antiquities and Fine Arts listed the bridge as a monumental building of national artistic heritage.

Hitler and Mussolini looked out over the Arno from the corridor's central windows during Hitler's visit of 9 May 1938. As the German troops withdrew before the advancing British Eighth Army on 4 August 1944, this was the only bridge in Florence not blown up. Historians credit the decision to the German command, taken by Hitler with the intercession of the consul Gerhard Wolf; the bridge was left standing but made unusable by wrecking the embankment and the houses at either end. Via Por Santa Maria, borgo San Jacopo and via Guicciardini were among the streets levelled. A rival account circulated in 2016 has goldsmiths cutting the wires of the charges; neither rests on firm evidence, though the first is better attested.

The Rossi-Cerchi and Consorti towers were rebuilt after the explosions. Consolidation works, studied by a commission appointed in 1949, began in 1960. The flood of 4 November 1966 damaged it again, bringing restoration in 1967–68 and strengthening of the piers and river bed in 1978–79. Between 2005 and 2006 the city council removed 5,500 love locks from the railings around the Cellini bust; attaching them now carries a fine. Closed to vehicles and designated a World Heritage Site, an announcement of April 2024 set out cleaning, an upgrade of the joints already installed and the strengthening of its stone and footpath.
