As always, the royal family and high-ranking courtiers within the palace had superior hygienic arrangements at their disposal. Louis XV's care for hygiene led him to install an early water closet, imported from England, in 1738. Known as an "English Place" ("Lieu à l'Anglaise"), the flush toilet was supplied with water from an overhead tank and emptied into a ground level drain, preventing lingering odors. By the mid-eighteenth century, other members of the royal family, the King's mistress Madame du Barry, and certain high-level courtiers had also installed their own water closets.
