John and Mary Marnach, with their son Nicholas, were immigrants from the commune of
Rambrouch in
Luxembourg. Many of their countrymen had settled in the communities of
Elba and
Rollingstone in
Winona County. Most of the settlers built simple, subsistence-style residences, but the Marnachs opted to employ construction methods hearkening back to medieval Germany. Farmers and stonemasons by trade, they constructed a home for themselves in four stages from 1857 to 1860. The house stood on a
stagecoach road between
Minneiska and
Plainview, Minnesota. It was part of the now-abandoned townsite of
Whitewater Falls. A wooden lean-to was added to the rear of the house in 1914. The house remained occupied for several decades, but by the mid-20th century it stood vacant. It was added to the National Register of Historic Places in January 1978. Descendants of the area's settlers spearheaded an international effort to preserve the deteriorating house, gaining the assistance of the Luxembourgish government and donations collected by Luxembourgish schoolchildren. From 1991 to 1993 craftsmen from Luxembourg worked with local volunteers to restore the Marnach House, replacing the roof, doors, windows, and shutters, reconstructing much of the west wall, replastering the interior, and installing new flooring. On August 12, 1993, the restored house was dedicated in a ceremony that included former Luxembourgish
prime minister Pierre Werner. ==Significance==
