Old St. Mary's Catholic Church

Old St. Mary's Parish is a Catholic faith community serving the downtown Detroit area, the business community, and those living in the region who are attracted to our community of faith.

Since 1893, the Holy Spirit Fathers [Spiritans] have faithfully served Old St. Mary's Church. The Spiritan Fathers continue to exercise their rule of Faith by making themselves advocates, supporters, and defenders of the weak and little ones

Old St. Mary's is a spritual oasis in Downtown Detroit. Daily Mass at 12:15 attracts the business community, government, court employees, and out of town visitors. The Church is open Monday thru Sunday prior to Mass until 2pm, at which time the outside
doors will be locked.

Before she gained the title "Old", St. Mary's was known for many years as the "Church of the Grottos." There are three: the grotto of Gethesemane, depicting Christ's agony in the Garden of Olives; the Baptismal Grotto, depicting Christ's Baptism in the Jordan River by John the Baptist complete with running water; and the Lourdes Grotto which is a replica of that French shrine.
