Casavant r alisait dans les instruments de cette dimension l' poque de sa construction.
The organ in St. Calixte Church is another fine example of Casavant's craftsmanship in the building of its instruments at the beginning of the 20th century. The organ case, with its dummy display pipes, is noteworthy for the meticulous and detailed work carried out by the craftsmen. Crowning the center tower of the organ case is a carved gilded statue of an angel sounding a trumpet, the work of famous sculptor Louis Jobin. The first organ was purchased in 1897 and was buit by Eus be Brodeur from St. Hyacinthe. Even before the final tonal adjustments, the organ was destroyed in a fire along with the church.
