Harmony’s first school, nicknamed the Little Red Schoolhouse, was a one-room structure built in 1864 in the village of Greenfield Prairie, a mile south of where Harmony would later be incorporated. The modest school, built by some of the area’s earliest immigrants, provided the foundation for what would become a thriving independent school district, a source of great pride, and a sign of prosperity for those living in and around Harmony for almost a century.
