The origins of the décor


The initial phase of the decoration planned by the architect, O'Donnell attracted much criticism. In fact, the decor during the early years, shows developments that are rather different to ones at present. 

Notre-Dame-du-Sacré-Coeur chapel


In 1889, the priest Léon-Alfred Sentenne entrusted the architects Perreault and Mesnard with the construction of a chapel for ceremonies gathering a limited number of people, such as weddings and funerals. Baptized “Notre-Dame du Sacré-Cœur”, it is inaugurated on December 8, 1891.
