The church was extended with this new facade in 1833.
The heritage value of Saint-Eustache Church lies in its historical associations, its location, and its architecture. During the Battle of Saint-Eustache on 14 December 1837 the church played a key role in the end of the Lower Canada Rebellion when the Patriotes used it as a defensive position. Many Patriotes also took positions in the nearby presbytery, convent and neighbouring houses. Having withstood cannonballs and musket fire, the church was destroyed by the fire that ended the battle, apart from the façade and base of the side walls. The attached sacristy was also destroyed by fire as were the presbytery and convent on either side of the church. Built in 1780-83 on a Latin cross plan with semi-circular apse, the church was extended forward when the present façade was added in 1831-33. The church was reconstructed following the 1837 fire with slightly higher walls and windows. Between 1842 and 1845 the facade and towers were repaired and new bells fitted. 1905-07 saw many changes,the aisles extended, the sacristy rebuilt, a chapel built behind the church, and the roof replaced. New bell towers were constructed and a small pediment surmounted by a statue of St. Eustace topped the new roof peak.Photographed by Cosmos Mariner, May 26, 20244.

Excerpt: Saint-Eustache Church National Historic Site of Canada is a Roman Catholic place of worship in the heart of the town of Saint-Eustache, Quebec, just northwest of the island of Montreal. Begun in 1780, this substantial stone church features a monumental neoclassical façade with twin spires and belfries. A small pediment surmounted by a statue of St. Eustace screens the roof peak. The façade exhibits damage inflicted during the battle of Saint-Eustache in 1837, when the church also suffered extensive fire damage. Rebuilt several times in its history, most recently in 1905-07, Saint-Eustache Church remains a powerful symbol of the Lower Canada Rebellion of 1837.(Submitted on March 26, 2025, by Cosmos Mariner of Cape Canaveral, Florida.)
