This video shows four of Grasse's streets as they were one hundred years ago, brought to life with the help of AI.  You can read more about them, their buildings and their history in my posts about rue Tracestel, rue Sans Peur and rue de la Rêve Vieille.  You can also read more about Joseph, the brother of the great photographer Nègre, and his close association with rue Charles Nègre, here.  Click to show the video (if you're using your phone, it's better in landscape mode).
