Immaculate Conception Catholic Church in Osakis, Minnesota was incorporated on August 11, 1899. Because Osakis was without a Catholic church before this time, families made the trip to nearby Belle River or West Union to attend Mass. ​After the church was completed, 45 families called Immaculate Conception their parish home.

​

Immaculate Conception church was dedicated by Most Reverend James Trobec of the St. Cloud Diocese on December 17, 1899. Following the dedication ceremony, Bishop Trobec celebrated a Solemn High Mass assisted by Father Ildephonse Molitor. The West Union choir and local singers provided the music. The Bishop preached a sermon first in English and then in German. The celebration came to a close with benediction.

​

The church had a seating capacity of 400 with a magnificent altar and two side altars to match.
