The Bridge of Sighs, in Italy known as the Ponte dei Sospiri, is located in the San Marco district near the Castello district. This bridge is probably the most important one in Venice, since it the connection from the Doge's palace to the prison on the other side of the Rio di Palazzo canal. The bridge, made of lime rock, was planned by Antonio Contin. Built in 1600, the constructions lasted until 1602/1603. The 11 meter long corridor is relatively narrow. Antonio Contin helped as well with the construction of the Rialtobridge by Antonio da Ponte.
The bridge functioned as the connection between both buildings to haul off people, who were convicted in the Doge's palace to the prison on the other side of the bridge. Within the bridge there are two with a wall separated ways, so that just convicted persons and potential convicts didn't see each other. Later the bridge got its name due to its function. The prisoners were thought to sigh a last time on their way into prison on the bridge with a look on the canal. That's why the bridge was called the Bridge of Sighs.
The famous bridge with it's romantic name make you believe that it's look pompous in the inside as well. However, due to the separating wall the inner part of the bridge is rather Spartan. The connection to the Prigioni nuove, the new prison, can be visited with a guided group or with a visit to the Doge's palace.
