This charmingly simple bridge is to Florence what the Tower Bridge is to London. It was built in 1345 to replace an earlier bridge that was swept away by flood, and its shops housed first butchers, then grocers, blacksmiths, and other merchants. But in 1593 the Medici grand duke Ferdinand I (1549-1609), whose private corridor linking the Medici palace (Palazzo Pitti) with the Medici offices (the Uffizi) crossed the bridge atop the shops, decided that all this plebeian commerce under his feet was unseemly. So he threw out the butchers and blacksmiths and installed 41 goldsmiths and 8 jewelers. The bridge has been devoted solely to these two trades ever since.

The Corridoio Vasariano (Piazzale degli Uffizi 6, Piazza della Signoria. 055/23885 or 055/294883), the private Medici corridor, was built by Vasari in 1565. Though the ostensible reason for its construction was one of security, it was more likely designed so that the Medici family wouldn't have to walk amid the commoners. The corridor is notoriously fickle with its operating hours; at this writing it was temporarily closed, but it can often be visited by prior special arrangement. Call for the most up-to-date details.

Take a moment to study the Ponte Santa Trinita, the next bridge downriver, from either the bridge or the corridor. It was designed by Bartolomeo Ammannati in 1567 (possibly from sketches by Michelangelo), blown up by the retreating Germans during World War II, and painstakingly reconstructed after the war. The view from the Ponte Santa Trinita is beautiful, which might explain why so many young lovers seem to hang out there.
