The French writer Alphonse Daudet (1840 - 1897) wrote a series of short stories called Lettres de Mon Moulin. Daudet did spend time in a windmill in Provence, but the stories are definitely fiction - and very funny!
In June I went on a literary pilgrimage to Fontvieille, a small town about 8km from Les Baux de Provence. Just outside Fontvieille you can find what's called 'Le Moulin de Daudet' - not the windmill where he lived (that's now a ruin, though you can walk to what's left of it), but a mill he featured in several of his stories.
The mill and the views are gorgeous and, as I discovered, it's a very pleasant place to sit and eat apricots, fresh from the market. The only thing I regretted was not having my copy of Lettres de Mon Moulin with me to read under the pines. I could probably have found it in the town, but it just seemed like too much effort to leave my perch ... however, my hint to you is: go on a sunny day, bring a book, buy a picnic at the market in Fontvieille and bask under the shade of the sails. Repeat as necessary.
