St. Michael the Archangel Parish was the 10th parish founded in the city of St. Louis. In 1849. a temporary church was erected to support the Irish population in North St. Louis. The new church at 11th and Jefferson (now Clinton) was blessed in December 1857. The school started in 1862-1863 and was staffed by the Sisters of Loretto. The Church and rectory buildings were razed in 1957 to make room for I-70 Mark Twain Expressway. Because the highway took only the church and rectory, masses were transferred to the the school building at 2501 North 11th. The school with only 60 children in the last class was closed in 1963. However, the building continued to serve as church and rectory until April 1975 when the parish was officially closed and its faith community merged with Most Holy Trinity. The school building now serves as the Greater Leonard Miss. Baptist Church.
