Harmony has long been known as “The Biggest Little town in Southern Minnesota”; discover the big history of this little town. The Harmony Area Historical Society is committed to the collection, preservation, dissemination and interpretation of knowledge about the history of the Harmony Area and its unique geology. The Historical Society has developed interpretive exhibits describing this history and geology. We have developed and supported permanent exhibits at the Harmony Visitor Center and along the Harmony - Preston Valley State Trail. In addition, the society creates temporary exhibits during the summer and special events during the year.
