The Mid-America Windmill Museum was created to fulfill that purpose. The museum is governed by an all-volunteer, 21-member Board of Directors who are elected by dues-paying members of the Kendallville Windmill Museum and Historical Society. The Board of Directors elects museum officers.

More than 50 American, water-pumping windmills have been restored and are on display in the museum barn and on the grounds, seen via a graveled walking path.

One highlight of the museum is a replica of the Robertson Post Windmill, a single stone wooden grist mill with a 52-foot diameter wind wheel. The original Robertson Post was shipped from England and erected on the James River near Jamestown, Virginia in the 1620s.
