It was designed by the Dubuque architectural firm of Fridolin J. Heer & Son.

The Sisters of St. Francis from Dubuque and lay teachers taught in the school, which had 640 students when it opened. Its early principals were laymen until 1952 when a Sister became the principal. A ninth-grade class for boys was begun in 1930 and tenth grade was added two years later. The high school program was discontinued in 1949 due to a teacher shortage.

Washington Street and East 22nd Street Historic District is a nationally recognized historic district located in Dubuque, Iowa, United States. It was listed on the National Register of Historic Places in 2015.

The focus of this district is a cluster of brick buildings around the intersection of Washington and East 22nd Streets on the north side of Dubuque. Its location west of the former Chicago Great Western Railway and the Chicago, Milwaukee, St. Paul and Pacific Railroad yards led to a large percentage of the residents here to be higher ranking railroad employees. The historic buildings are brick and frame houses, with the exception of one brick storefront/residence. Most of the houses are front or side gabled vernacular structures, and a few that are Italianate or Classical Revival. Couler Creek, which was located behind the houses on the east side of Washington Street, also affected the development of this area. There is no alley behind the houses on the east side of Washington.
