Château de Beauregard, La Celle-Saint-Cloud 1.81

Château de Beauregard is a former house in La Celle-Saint-Cloud south-west suburbs of Paris, 5 km north of Versailles.
The name of the domain seems to have its roots in the Middle Ages. The château was built on a top of a hill between La Celle-Saint-Cloud and Le Chesnay. In the early 17th century, the house was owned by the du Val family, Pierre du Val was the House master of king of France. Then the château was the property of the Montaigu family, which rented it. During the Revolution and Empire eras, ownership of the château changed often.
In the mid 19th century, Harriet Howard bought the house and its park. She also bought the Béchevet farm and the Bel-Ébat stud farm, marking a very large 184 ha property. The château was in a poor condition; she rebuilt it in a neo-classical style. She also enclosed the whole area with a wall. From this château, she worked for the success of Louis-Napoleon Bonaparte, of whom she was mistress and financial backer. She died in 1865.
Her son Martin-Constantin Haryett, created comte de Béchevet by Napoléon III, was a spendthrift, and had to sell the château in 1870 to the duchesse de Beauffremont.
