St. Mary's School
In 1870 Father Camillius Maes of Saint Peter Parish erected Saint Mary's school on this lot, adjacent to the Church. When the grammar school opened in that year, it was the first Catholic school in the city and in Macomb County. Three nuns from the Immaculate Heart of Mary Convent in Monroe were chosen to teach the students, eighty in the first year. The school was a two-room, two-story wooden structure. The boys were taught in one room and the girls in the other. All received instruction in basic elementary education subjects and chuch doctrine. By 1882 Saint Mary's numbered about 170 students. The first class -- all girls -- was graduated in 1885. The boys had their first graduation in 1909. The sisters of the Immaculate Heart of Mary taught at the school until 1986, when lay teachers look over the instruction.
