The Bridge of Sighs (Ponte dei Sospiri) is an enclosed limestone bridge in Venice connecting the Doge's Palace to the historic New Prisons, built in 1614 in the Baroque style. Famous for its romantic legend and distinctive white stone facade, the bridge contains two separate internal corridors running side by side. One linked the courtrooms to the prison cells; the other connected the prisons to the offices of the State Advocacy and the Parlatorio. Both corridors also connect to a service staircase leading from the ground-floor Pozzi cells to the infamous Piombi cells under the lead roof. The romantic name dates from the 19th century, when Lord Byron popularized the idea that prisoners would sigh at their last glimpse of the lagoon and San Giorgio island through the bridge's small stone-grilled windows before heading to their cells. The reality was more bureaucratic than poetic: most prisoners crossing the bridge were headed to relatively minor hearings. Still, the legend stuck. You can see the bridge from the outside at two points: from the Ponte della Paglia on the waterfront near Piazza San Marco, or from the small Ponte della Canonica on the other side. Walking through the bridge's interior is part of the Doge's Palace visit, which is the only way to experience the narrow, enclosed corridors firsthand.
