One of my favorite things about traveling throughout France is the odds of falling upon a 12th century mill on a nicely travelled road are quite high. This particular one used to be a part of the pilgrimage stops on the way to Carmino de Santiago of Compostelle. Aside from that, I do find its simplicity is what makes the ancient mill so beautiful.
I would love to spend time discovering all of the ancient relics of France, it makes me see time and history differently, more along the lines that the more things change, the more they stay the same. We might like to think of ourselves as evolved, but underneath all of the new technology we are still made of the same stuff; fear, uncertainity, love, doubt and unfortunately hate.
Walking along these old monuments puts these thoughts first and foremost in my mind.
