The former Mandan High School has been listed in the National Register of Historic Places, a list of properties the federal government considers worthy of preservation and recognition.
Most recently known as Mandan Junior High, the property was nominated at the local level for its architecture.
Original buildings were designed by Gilbert R. Horton in 1917 and 1924 in Tudor/Collegiate Gothic style. Subsequent additions were designed by three North Dakota architecture firms.
The property is also significant for its ability to tell the story of education in Mandan. At times, it housed a high school, a junior high school and an elementary school.
Entry into the National Register of Historic Places gives a property a measure of prestige, provides protection from adverse effects in federally assisted projects and provides eligibility for certain preservation financial incentives.
