The Sweetest Heart of Mary Roman Catholic Parish Local Historic District consists only of the church at 4440 Russell Street. You can read details about this church in the Sweetest Heart of Mary Roman Catholic Parish Local Historic District Final Report (local copy), which I recommend highly to anyone interested in Detroit's history.

My photos of this church can be seen in this slide show.

A Wikipedia Page also describes the church, as well as HistoricDetroit.org, and www.motherofdivinemercy.org.
