The Bridge of Sighs is a bridge in Venice that creates a connection between the prison and the Palazzo Ducale (Doge's Palace). It crosses the Rio di Palazzo canal and is made of limestone.
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.
