Cromwell Consolidated School was built in 1921 by Sublett & Hafner contractors for a sum of $9.000. It consisted of four classrooms with a basement housing a coal furnace. The school originally had grades 1-10, and grades 11 and 12 were added in 1924. In 1929, a gym, two classrooms, and a stage were added. Later, a hand-dug basement under the original four rooms housed a kitchen, lunchroom, classrooms, and restrooms. In 1955, grades 9-12 were moved to Beaver Dam High School, while grades 1-8 stayed at Cromwell until the school burned on Feb. 28, 1969. Students finished the school year in local churches. In 1970, the community purchased this land for a ball park and playground.
