Nicholas Marnach House, Whitewater State Park

The Nicholas Marnach House is the restored home of a Luxembourgian pioneer family in Whitewater Township, Minnesota, United States, built 1857–1860. It was listed on the National Register of Historic Places in 1978 for having state-level significance in the themes of architecture and exploration/settlement. It was nominated as Southeast Minnesota's oldest surviving example of the traditional European construction occasionally produced by the region's Germanic immigrants. The house is about three miles north of Elba, Minnesota, within the Whitewater Wildlife Management Area, a state wildlife preserve adjacent to Whitewater State Park. ()
