History

Built in 1796 by militia captain Joachim Génus using log-on-log white pine construction, the house was sold to Joseph Valois between 1830 and 1838. The Valois family owned it for more than 100 years, which is where its common name comes from. It was later sold to Patrick Brunet in 1931, then acquired by the City of Dorion in 1970, restored in 1972, and classified as a heritage property.
