Shame on someone.

Not a post i wanted to put on but feel that even in this part of remote France we're not exempt from what I think is a terrible world wide problem.
For 140 years the bridge at Le Moustier has spanned the river Vezere with the only changes to its stonework being a carving of a flood level in March of 1930. A few days ago, along comes someone with a few cans of spray paint to put his/her 'mark' on these pieces of old stone.
I have never liked the graffiti in places like Barcelona, Amsterdam or anywhere else in the world, all i can say is shame on whoever is responsible.
