The Château de Bénouville is a building in Bénouville, Normandy, near Caen (northern France. It was designed in 1769 by architect Claude Nicolas Ledoux and built in 1770-74 and 1776-80 at the request of Hyppolite-François Sanguin, marquis of Livry (1715–1789) and his marquise Thérèse Bonne Gillain de Bénouville, heiress of the property. The interior was under construction from 1778 to 1780 under the direction of Jean-François-Étienne Gilet, the architect of Caen. In 1792, it was purchased from the widowed marquise by a fermier général (tax collector) who was guillotined in 1794. His daughter inherited the property which remained in that family until 1927. It then became the property of the general council of Calvados which turned it into a maternity hospital (singer Gérard Lenorman was born there).
