After Magpie moved to Dubreuilville, it took more than a decade for mass to be celebrated in a church. The altar was carved from a large tree trunk and the church had a lectern, baptismal font, tabernacle base and wooden pews.
The frame of the building consists of circular ribs, originally built on the ground and then cut in half. The ribs form the arches that give the church its unique shape. One of the brothers, Joachim, made the colored windows behind the altar, which are still there today.
