After a few days in the mediterranean sea (in the island of Malta), I'm back to the big city of light! All French cities have signs like this at their entrance, but in Paris, it's actually pretty rare to see them. When I see one, it reminds me of an old uncle who used to tell me about the Paris Octroi, a toll that was collected at each gate of Paris (the main entrances are called gate in Paris) until 1943 on certain goods.,. Now it does not exist anymore, but they found other ways of taxing people!!
