Why is the bridge in Venice, named the bridge of sighs?

This was an enclosed bridge that linked the Doge's prisons with the inquisitor's rooms in the main palace. Supposedly the name was inspired (with the help of Lord Byron) by the sighs of condemned prisoners as they were led through it to the executioner. Actually, by the time the bridge was built, the days of inquisitions and executions were over, and the cells under the palace room held mostly small time crooks.

Yes thanks for the information on this you did a great job. The bridge was built in 1600..before my time
