This bridge dates back to a time when bridges were often inhabited, as this one still is. It's a very old bridge.
The houses on the bridge are actually cantilevered over the side of the bridge, in order to maximize the amount of usable space created by the relatively narrow bridge.
Notice that the height of the bridge blocks the view of the river from other locations.
The zigzag gallery that starts in the foreground and runs across the bridge was built as a private walkway for a rich Florentine. Talk about snobbery!
