One of the more interesting bridges in Florence was the Ponte Vecchio. It is for pedestrian traffic only and is the oldest bridge in Florence crossing the river, Arno. The view down or upriver from the center of the bridge is wonderful. The whole bridge area contains nothing but specialty stores, selling jewelry of all kinds.
I came home with two rings as souvenirs, and I would love to have gotten more. I also have a wonderful picture of the bridge on my wall at the top of the stairs at home. Wonderful memories! The bridge was built in 1565. During the summer, there are street performers and portrait artists along the bridge. It does get very crowded with people during these times, however. But it is not to be missed!
