Gondolas are traditional flat-bottomed rowing boats suited to the conditions of the Venetian Lagoon. For centuries, they were the chief means of transportation within Venice. In modern times, the iconic boats still have a role in public transport in the city, serving as traghetti (ferries) over the Grand Canal. Their primary role, however, is to carry tourists on rides at established (i.e., very expensive) prices. Here, they are parked by Piazza San Marco, waiting to glide once again on the glorious Venetian Lagoon.
