Ponte Vecchio is Florence's oldest bridge and one of the most recognisable structures in Italy — a medieval corridor of jewellers' shops jutting out over the Arno River on wooden brackets, looking exactly as improbable as it sounds. Built in its current form in 1345, it replaced a series of earlier bridges destroyed by floods, and the design by Neri di Fioravanti has somehow held firm ever since, surviving even the Nazi retreat of 1944 when it was the only Florentine bridge left intact — reportedly on Hitler's direct orders, though historians still debate this. Whatever the reason, the city owes its most beloved postcard view to that fact.
For most of its history the bridge hosted butchers and tanners, drawn by the convenience of the river for dumping waste. That changed in 1593 when Ferdinando I de' Medici, apparently tired of the smell, evicted them and reserved the shops exclusively for goldsmiths and jewellers — a tradition that continues today. Running above the shops is the Vasari Corridor, a private elevated walkway commissioned by Cosimo I de' Medici in 1565 so the ruling family could move between the Palazzo Vecchio and Palazzo Pitti without mixing with the public. You can occasionally visit the corridor on guided tours, though access has been intermittent in recent years.
The bridge is worth visiting for the spectacle of it — both on the bridge itself, jostling through tourists between gleaming display cases, and from the riverbanks or the nearby Ponte Santa Trinita, where the view of Ponte Vecchio reflected in the Arno is one of those sights that genuinely earns its reputation. At golden hour the warm stone and overhanging shops glow in a way that photographs but doesn't quite capture. Come early morning if you want any chance of experiencing it with breathing room; by 10am it's dense with visitors.
Practically speaking, the bridge is open to pedestrians at all hours and costs nothing to walk across — the expense comes only if you browse the jewellery shops, which range from artisan goldsmiths to high-end boutiques. The lock-and-key ritual of padlocks on the bridge was banned years ago and enforcement is real, so skip that idea. If you're buying jewellery, the goldsmiths with workshops rather than just retail fronts tend to offer more interesting and fairly priced work — look for signs indicating a laboratorio on the premises.
