The Kregel Windmill Factory Museum is housed in the last, intact historic windmill factory in the United States. The Kregel Windmill Company operated out of this factory from the time it was built in 1903 to Art Kregel’s death in 1991. In total the business ran for 112 years on Central Ave here in Nebraska City. The museum opened on April 26th, 2013 after an extensive two-year renovation. The main gallery is designed in such a way that visitors can walk through the Kregel Windmill Company factory and see it in an untouched state, appearing as though the workers simple left for lunch and never returned. The museum features seven interactive video kiosks that guide visitors through the gallery. Like many of the museums in Nebraska City, the Kregel Windmill Factory Museum is listed on the National Register of Historic Places.
