This was the home of Joseph Papineau, a notary and politician who lived from 1752-1841. The house remained in the hands of the Papineau family. Joseph's son, Louis-Joseph Papineau (1786-1871), was a politician and leader of the Patriotes who objected to British rule. He had to go into exile for a number of years before he was pardoned. You can see a winter photo of Papineau House. I had the pleasure of attending a concert in the house's gardens. It is wonderful when our historic buildings are put to many uses.
