The Ponte Vecchio bridge in Florence, Italy, was originally built by the Romans in 996 AD, rebuilt after a flood in 1117, and constructed again in 1345 after a second massive flood. This third bridge, known as the “Old Bridge” not only serves as a way to cross the river Arno, but also as a center of commerce with over four dozen shops on multiple levels, some even projecting out over the river. Known for its beauty and interesting history, it was the only bridge on the Arno in Florence not destroyed by the German army in World War II. Hitler ordered it spared because of its beautiful views.
