During a daylong bike ride, we passed through the village of Lagraulet-du-Gers and spotted this unusual water tower covered with an elaborate mural. Only later did we learn that it was converted into a bed and breakfast by the town’s mayor, called Le Château D’Eau Lagraulet. There is the main room, dubbed a “bedroom beneath the stars.” And roof is a terrace where breakfast is brought each morning. Jean-Paul Chambas is the artist behind the fresco. Depending on which days and the length of the visit, prices range from €90 per night to €150 per night.
