Nicholas Marnach House

The Nicholas Marnach House stands as a two-story limestone structure with three-foot-thick walls, featuring a half-hip roof and traditional European construction techniques adapted to the Minnesota landscape.

Built between 1857 and 1860 by Luxembourgish immigrants and added to the National Register of Historic Places in 1978, this residence represents the oldest surviving European-style farmhouse in Southeast Minnesota.

Constructed by the Marnach family from Luxembourg, this house exemplifies the architectural traditions and settlement patterns of Germanic immigrants who brought medieval European building techniques to 19th-century Minnesota.

Located within the Whitewater Wildlife Management Area near Whitewater State Park, the house can be accessed year-round on foot with limited on-site amenities and no dedicated parking facilities.

This fieldstone farmhouse remains the only intact European-style residence of its size in Southeast Minnesota, featuring mortise and tenon timber framing and walls reaching up to three feet in thickness.
