It is not only the world’s most expensive house (up for sale for a reported $1.1 billion), but this 19th-century gem also has a spectacular history. Situated in Saint-Jean-Cap-Ferrat, France, Villa Les Cedres is surrounded by a 35-acre garden which has been deemed a national heritage site by France’s government and wwas originally designed by the dame man who designed the garneds of the Eiffle Tower and Champs Elysees; it features Olympic-size pool, 10 bedrooms, 30 stables, and its own chapel. Built in 1870, in 1904 it was purchased by King Leopold II, and in 1924, it was acquired by the Marinier-Lapostolle family, which created Grand Marnier, but when Campari bought the liquor in March for $760 million, it got the digs and has decided to sell. Among the celebrities hosted in the estate were Charlie Chaplin, William Somerset-Maugham, Elizabeth Taylor and Richard Burton, and Prince Rainier III of Monaco. With this tag price, it would be the most expensive residential real estate sale ever, surpassing Chateau Louis XIV, a mansion outside Paris that was sold for a record 275 million euros in December.
