About this city
Also known as: The Biggest Cave Town in Minnesota
Harmony is a picturesque, culturally progressive historic rural town located in Fillmore County, southeastern Minnesota, nestled within the state's beautiful rolling bluff country. Settled in the 1850s, the town center is framed by an exceptionally charming country personality, defined by deep agricultural roots, historic limestone storefronts, and sprawling organic heritage farms. Harmony is globally recognized as the proud host of Niagara Cave, one of the premier geological subterranean wonders in the United States. Bordered by Minnesota's largest Old Order Amish community, the town expertly preserves a slow-paced, welcoming Midwestern country lifestyle where deep subterranean exploration, river-valley bike trails, and rustic pioneer traditions seamlessly meet.
