The Bridge of Sighs (Ponte dei Sospiri in italian) is a bridge located in Venice. The enclosed bridge is made of white limestone and it is the most famous along with the Rialto Bridge. Beautiful on the outside and impressive inside, it connects the Doge's Palace with the second floor of the Palace of prisons, built in the seventeenth century because the cells of the Ducal Palace that were on the ground floor had become inadequate and unsafe.
The architect Antonio Contino designed it so that the prisoners couldn't escape. Tradition says that the prisoners sighed seeing for the last time the freedom, tradition now transformed with the sigh of passion for of lovers who, passing under bridge with the Gondola, they promise to each other eternal love.
