Marie de Rabutin-Chantal, marquise de Sévigné was a patient in 1676 and 1677 and would popularize Vichy's Thermal Baths through the written descriptions in her letters. The Vichy waters were said to have cured the paralysis in her hands, thus enabling her to take up letter-writing. In 1761 and 1762, Adélaïde and Victoire of France, the daughters of Louis XV, came to Vichy for the first time and returned in 1785. The bath facilities seemed extremely uncomfortable to them because of the muddy surroundings and insufficient access. When they returned to Versailles, they asked their nephew Louis XVI to build roomier and more luxurious thermal baths, which were subsequently completed in 1787.
