Holy Name of Mary Pro-Cathedral, Sault Sainte Marie

Holy Name of Mary Proto-Cathedral, also known as St. Mary Proto-Cathedral, is a historic Roman Catholic parish church in Sault Ste. Marie, Michigan, United States that was formerly a cathedral church and the first Cathedral, hence "Proto-Cathedral", of the Roman Catholic Diocese of Marquette. It is the oldest parish and oldest cathedral parish in Michigan, and the third oldest parish in the United States. While the present church edifice, the fifth for the Parish, dates from 1881, the Parish began in 1668 as a Jesuit mission. It was listed on the National Register of Historic Places in 1984 and designated a State of Michigan historic site in 1989. The Proto-Cathedral was the Cathedral of the Diocese of Marquette when it was denominated the "Diocese of Sault Sainte Marie", which diocesan title is presently that of a titular episcopal see. ()
