We passed through Chalons sur Saone, known for being one of the authorised crossing points of the Demarcation Line which divided unoccupied France from occupied France in World War 2.
The historic trace of the line itself was marked only by a rather insignificant road sign on the road bridge over the river.
However, in the town I saw this building about which I can tell you nothing.
I know not its history or its purpose but this did not stop me from gazing in awe at the stone decoration on its facade.
If you know anything about the building, do enlighten me.
