The Bridge of Sighs is a limestone bridge in Venice that connects the Prison to the Palazzo Ducale (Doge's Palace). It crosses the Rio di Palazzo canal.

The bridge was built in 1600 under the supervision of Antonio Contino, the nephew of the architect of the Rialto Bridge.  

The name stands from the stories that prisoners would get a quick glance at the beautiful city when being moved back from the Palace to their cells.
