History and setting
The château was built around 1850. It was a private home for several families, then a retirement home from 1988 for up to 40 residents, before closing for about fifteen years. Salma and Lionnel Joussemet, two engineers who sold their technology start-up, bought it and moved in during the summer of 2023, restoring it with modern comfort, safety and accessibility standards. The château overlooks the Château de Gaillon, the first Renaissance château in France. Giverny is 18 km away, Les Andelys 13 km and Rouen 41 km.
