The Church of Saint-Léon-de-Westmount (French: '''Église Saint-Léon de Westmount''') is a Roman Catholic church located in Westmount, Quebec at 4311 De Maisonneuve Boulevard West. Built in 1901, the church was designed by well known Montreal architect Georges-Alphonse Monette and decorated by Guido Nincheri from 1901 to 1903, using the wet plaster buon fresco technique.[1] Designed in the Romanesque Revival style, and featuring an Italianate façade with bell tower, the Church of Saint-Léon-de-Westmount was designated a National Historic Site of Canada in 1997 and plaqued in 1999.[2]
Romain Pelletier was notably the church's organist from 1909 to 1951.[3] His brother Frédéric Pelletier also briefly served as choirmaster at the church.
