Saint-Denis-sur-Richelieu

Saint-Denis-sur-Richelieu is a municipality in the southwestern part of Quebec, Canada, on the Richelieu River in the Regional County Municipality of La Vallée-du-Richelieu. The population as of the Canada 2011 Census was 2,285. 

In 1694, King Louis XIV granted the Seigneurie of Saint-Denis to the aristocratic French Army officer Louis-François De Gannes, sieur de Falaise of Buxeuil, Vienne, France. He named his seigniory after his wife, Barbe Denys.

A great stone Roman Catholic Saint-Denis Church was completed in 1796.

On November 23, 1837, Saint-Denis-sur-Richelieu was the site of the murder of British courier Lieutenant George Weir by Patriotes. Subsequently, the Patriotes, calling themselves The Sons of Liberty based on the American model, won a battle against the British Army that marked the official beginning of the Lower Canada Rebellion. Today, Saint-Denis-sur-Richelieu has a museum called the Maison Nationale des Patriotes. This interpretation centre presents a history of the Patriotes movement led by the villager's most famous resident, Wolfred Nelson.

On October 21, 2012, a monument to the memory of Louis-Joseph Papineau was unveiled in a park next to City Hall, along the river, by Québec Premiere Pauline Marois.
