Crown land since 1802, this lot was granted to Philemon Wright in 1824 and integrated into the vast Britannia farm which then extended from the current rue des Orchidées, in Gatineau (Hull sector), to the old club Chaudière golf course, near the Aylmer sector.
In 1872, the lot was sold to David Moore Jr., neighbor of the Wrights to the east, and was part of the Moore farm for more than 20 years.
In 1906, Annie Louisa Augusta Moore sold the land to repay a debt and three days later, Nicholas Slater bought it to operate a dairy farm. During the 1920s, in the fall, gypsies would set up their trailers on the property during race week of the Connaught Park.
In 1929, one of Nicholas Slater's sons sold part of the lot to Gordon Stewart, a wealthy Ottawa entrepreneur who had an imposing stone house built there, Stoneleigh, where he lived with his wife and two daughters until he died in 1941.
In 1954, the two Stewart daughters sold the property to E.S. Sherwood, a Rockcliffe realtor, who sold it two years later for $ 82,000 to Nicholas Monsarrat. The author of the famous novel The Cruel Sea lived there for two years with his wife and two sons while he ran the Canadian office of the United Kingdom's Information Service. In his book, Life is a Four-Letter Word, Monsarrat says he adores his house and the lifestyle one experience there, despite the 'grotesque' amount of expenses involved in heating, repairs, caring for the many elm and maple trees. In 1958, he sold the property for $ 105,000 to Fay Loeb, the spouse of Julius Loeb, president of the Loeb and IGA stores.
In 1970, Mrs. Fay Loeb sold part of the property to the firm Place Lauzanne Ltée of Hull. Two years later, two notaries from Hull, Guy Lesage and Charles-Henri Rioux, along with Place Récamier Ltée, acquired it.
In 1974, the property was sold to Goldlist Construction Ltd. In 1976, when the company decided to build condominiums on the land, Goldlist created the Association récréative « Les Jardins du Château », a non-profit organization. The Château was then sold as a recreational and community center for co-owners of the condominiums as part of the entire real estate complex.
