No way let me hasten to assure you that I did not frequent the art galleries. In fact I didn’t spend much time indoors at all! But found some interesting art nevertheless.
In a short cul-de-sac near my hotel, a sculpture: River Man (sorry, I didn’t write the name in French)

And away from the old town, down on the lower side of the hill, the freeway rises with an exit to the upper level, leaving a forest of pylons which have become a feature of street art.
And very little tagging graffiti.
