French Mediterranean Coast

We all know the song 'Sur le Pont d'Avignon l'on y donse, l'on y donse...' or you do if you did Year 8 French. Here is what remains of the Avignon Bridge from the riverside but of course we had to walk out on it so we could dance to the song! Only kidding about the dancing but we did walk out on it. Notice it doesn't go all the way across the river?
