Its name is said to come from the small barrels that collected the water. Mentioned in 1559 as « source de la Frayneuse », it was exploited from the beginning of the 17th century, then brought back into prominence in 1753 with nearby baths. Too far from the center, it lost its spa-goers after the opening of the town's thermal baths. The glass rotundas, designed by L.-J. Devivier and William Hansen and completed in 1884, house the spring and a restaurant.
