The chalets of la Glière, in addition to serving as alpine chalets (shelter for the shepherds and cheese-makers during the summer), provided overnight shelter for excursionists before the creation of the refuges. The walls on both sides of the road served to contain the mountain pasture herds but also to prevent the transhumant flocks from dispersing across the private pastures. Since the seventeenth century, their pastoral use is attested by stones engraved by successive herdsmen and shepherds. Some engravings date back to the Middle Ages and even to protohistory!
