Very sad day and view...!
With this smoke seen from my window, centuries of history goes up in flame! The Cathedral of Paris is ablaze, and I believe the worst is yet to come, as the stone work will be hit by the high temperature (it wasn't a great quality of stone to begin with).
I could have walked to take some dramatic pictures, but I believe it was better not to add to the crowd viewing the blaze and maybe hindering firemen and police work.
This smoke slowly drifting in the sky of Paris, is for me, more appropriate, as a reminder of how civilizations can be mortal too, and that nothing is really eternal. With this smoke goes Victor Hugo and all the ghosts of Paris that was...
