In 1977, Le Pen inherited a fortune from Hubert Lambert (1934–1976), son of the cement industrialist Leon Lambert (1877–1952), one of three sons of Lambert Cement founder Hilaire Lambert. Hubert Lambert was a political supporter of Le Pen and a monarchist as well. Lambert's will provided 30 million francs (approximately 5 million euros) to Le Pen, as well as his opulent three-storey 11-room mansion at 8 Parc de Montretout, Saint-Cloud, in the western suburbs of Paris. The home had been built by Napoleon III for his chief of staff Jean-François Mocquard. With his wife, he also owns a two-story townhouse on the Rue Hortense in Rueil-Malmaison and another house in his hometown of La Trinité-sur-Mer.
