"On the square in the hamlet of Rieisse, you'll be able to admire a communal oven. The gable of the house right next to it has gutters which lead into a former cistern inside. All the rainwater from the roof converged on this tank, inside the kitchen, via gutters that were made first of wood and later of zinc. The cistern has a depth of 2 to 5 m and a capacity of 10,000 to 30,000 litres. When the foundations of the sheepfold were dug, Roman pottery for keeping resin was found. Indeed, whenever pine trees were felled, the resin was extracted and sent to the coast, where it was used to caulk boats. (M.P Leroy-Delmer)
