The parish was founded by the pioneer priest, Father Samuel Charles Mazzuchelli, who served as pastor of the parish from 1835 to 1843, and during this time directed the building of a church. This building served until it was destroyed by a fire which had consumed a good portion of downtown Galena.

Father Mazzuchelli began working with St. Michael's parish to build a new building to replace the one lost in the fire. Designed in the Romanesque Revival style, this is the largest church designed by Father Mazzuchelli. The new building has a truss formation to hold the weight of the roof, which helped eliminate the need for pillars within the church. This building still stands today, and continues to serve as a place of worship.

The current rectory was built in 1896.
