Following in the footsteps of his uncle, Antonio da Ponte, Antonio Contin was an architect in Venice. The only work he is well-known for is the Bridge of Sighs, which connects the Doge's Palace to the New Prison. Although he designed the bridge, he did not live long enough to see it finished; it was completed 2 years after his death. Much of his other work was with his uncle. He assisted with rebuilding the Rialto Bridge his uncle designed, and he took over the New Prison project after his uncle's death.
