Welcome to the Minidoka County Historical Society Museum! The Minidoka County Museum was founded in 1970. We are located just east of the fairgrounds at 99 E Baseline in Rupert, Idaho. The summer hours for the museum are 10am to 3pm Tuesday through Saturday. Winter tours are available by appointment. The museum is free but donations are appreciated. The museum houses digitized information and artifacts from the people who lived in Minidoka County in earlier generations. Come visit us and learn about the history of the county!
