In 1472, the Trebbia river flooded, partially destroying a bridge at the northern Italian town of Bobbio.
Art Historian Carla Glori is convinced that minute details included by Leonardo da Vinci in the background of the Mona Lisa are a reference to that event, and therefore the mysterious background, including a bridge that resembles Pointe Gobbo, is Bobbio.

Now, of course, there are many, many other theories of the location of the painting, including that it was all in The Master’s head, but I liked this one because it made for a good contest!!
