The Hazel Glen one-room schoolhouse was originally constructed in 1912 to serve students in Washington Tonwship in western Ringgold County. When the county school was closed, the building was moved to the school grounds in the county seat of Mount Ayr where it was used as a classroom until 1979. The century-old school has since been restored and is now part of the Pioneer Museum complex in Ellston. It’s open summer Sundays from 1:00 to 4:00 or by appointment at (641) 464-2140.
