Maison du Fontainier

Hidden in plain sight on Avenue de l’Observatoire stands the Maison du Fontainier. This unassuming building holds a secret history of water and royal privilege. The Maison du Fontainier wasn’t always just a house. It was the endpoint of a grand engineering feat, the Medici Aqueduct. Built between 1619 and 1623, the Maison du Fontainier marked the 27th ‘regard’ of the aqueduct. These ‘regards’ were small buildings used to inspect the water flow. The Maison du Fontainier, however, was more than just an inspection point. Its upper levels housed the king’s fountainier, Thomas Francine. Imagine him, living right above the source of the city’s water. Below, in the building’s cool cellars, the water flowed into three distinct basins. One basin, the Bassin des Carmélites, supplied water to the clergy, about 31% of the flow. Another, the Bassin du Roi, provided water for the Palais du Luxembourg and its fountains. This took the lion’s share, about 41%. The final basin, the Bassin de la Ville, supplied Paris’s public fountains with the remaining 28%. The Maison du Fontainier served this vital role until 1870. The construction of the Vanne Aqueduct rendered it obsolete. Despite its retirement from water management, the building retained its historic significance. In 1994, the Maison du Fontainier and its cellars earned a prestigious title. They were classified as a historical monument, ensuring its preservation for generations to come. So, the next time you stroll along Avenue de l’Observatoire, take a moment to appreciate the Maison du Fontainier. It’s a hidden gem, a quiet testament to a time when water flowed through a king’s fountainier and into the heart of Paris.
