Ponte de la Feltrina, San Marco. Many thanks to Sophie for pointing out the presence of the two gargami at the bottom of the photo.
The gargami (made of Istrian stone) were used to close the canals to the flow of water and clean them. They were the creation of Eugenio Miozzi, the same engineer who designed the Rio Novo and Ponti della LibertÓ, dell'Accademia and degli Scalzi.
