Venice is famous for its Grand Canal and its gondolas. But the men who build them are having trouble finding places to do so. And that is because of all the tourists.Only a handful of the traditional workshops remain in Venice. Squero di San Trovaso is the most famous. A gondola has up to 300 parts and takes two to three years to construct. The boatbuilders say that pizzerias and souvenir shops have an easier time getting a license than they do.
