Porta Fiume
One of the doors that mark the city walls. Dating back to the XIV century and restored after being damaged during the second world war, has a rectangular shape and it's open at the pedestrian crossing. From here there is access to the Bridge of St. Martin, built in the X - XI over the river Savio and ending originally at a subsequent port which is now destroyed. Over the years the river has also changed its riverbed, and the bridge passes, now, over a road.
