Old St. Mary's Catholic Church

Old St Mary’s is the third oldest Roman Catholic Church in Detroit and the first German Church. It was first built on the present site in 1841 by a parish of German Catholic immigrants at a time when the total population of Detroit was not much over 5,000. Not including labor, the original brick church cost a little over $239. The present church, replacing the earlier structure, was constructed in 1884, and styled in Victorian Gothic by Peter Dedericks, a native architect. The beautiful polished columns inside are of solid granite and impossible to replace today. The cornerstone for the First Church, built on the same site as the present site as the present stone, was laid on the feast of Corpus Christi, June 19, 1841.

Parish Homecoming

Please join us at the 11th Annual Old St. Mary’s Homecoming on Sunday, September 7, 2014 at the Noon Mass, followed by food, refreshment and fellowship under the tent in our parking lot next to the Parish Center.

All present, past and future parishioners are invited to this special Mass and gathering to see what is now happening at Old St. Mary’s – in the heart of downtown Detroit!

Make Old St. Mary’s Your Center Of Worship

OSM is a home for lovers of Catholic tradition, devotions, and Church music. Experience the presence of the Lord and pray where peace and tranquility lies!

Daily Mass at OSM is 12:15 pm, and the Sacrament of Reconciliation is available every day of the week — 365 days of the year. Here, many miracles and cures have been attributed to our Blessed Mother’s intercession (testimonial plaques are on the back wall of the church — read our History ).

As Mary was the one chosen by God to bring her son into the world, let us show our affection to her by welcoming Jesus into our Hearts. May you bear the light of His Love!

- Fr. Wayne Epperley, Pastor
