After Renovation

Probably the best known log house remaining in the county today is the Boerjan Log House, presented to the Mitchell County Historical Society by John and Marie Boerjan, on whose farm it was located. This fine example of a native log house was built by, we speculate, the Gilbertsons in the late 1850's, and was used by tenants of the Gilbertson family, visitors, and in more recent years it rented as a place of abode. Thoughout it's history wood siding was added, plaster walls created inside, an addition was added and the current stairs were located inside the addition. It was occupied until the late 1940's. The Historical Society moved it, from its' original location on the John Boerjan farm, south of St Ansgar, to the Mitchell County Fairgrounds in 1965 for preservation and display. Prior to the move, the siding was removed, the kitchen room torn off, and the plaster walls inside removed. A two story house was not as common out here on the prairie as the typical single room cabin.

In 2018 a restoration project was undertaken to repair and improve the Log House. Much of the work has been completed with new roof, new siding, new chinking, new doors and windows, all in an effort to re-create the Log House as it originally would have been built.
