Located in the northern part of the island that bears its name, Noirmoutier is separated from the rest of this island land by salt marshes. Our Galaxy is hardly perceptible to the naked eye because of the lights of the communes bordering the island. Here it is l'Epine that illuminates the sky. Fortunately, the two giant planets Saturn and Jupiter manage to compete with the artificial lighting, reflecting themselves in the salt saturated water of the marshes.
