In the old days in Provence, flocks of sheep were marched hundreds of miles, to cool mountain pastures, where they would graze during the hot summer months. They passed through village after village in what was called the transhumance, and all the villagers would come out to watch the spectacle.
In the 1960s and 70s, the transhumance faded away as shepherds began to transport their flocks by truck, but then towns like St-Rémy-de-Provence revived the tradition with annual festivals. Held every year on Whit Monday, the modern transhumance features thousands of sheep circling the town, along with shepherds, sheepdogs and the occasional goat. It is like a river of sheet flowing past, a sight not to be forgotten!
