The Bridge of Sighs (Italian: Ponte dei Sospiri) is a bridge located in Venice, northern Italy. The enclosed bridge is made of white limestone, has windows with stone bars, and passes over the Rio di Palazzo and connects the New Prison (Prigioni Nuove) to the interrogation rooms in the Doge's Palace. It was designed by Antonio Contino (whose uncle Antonio da Ponte had designed the Rialto Bridge) and was built in 1600.
