Laurens Polygonal Hog House

The Laurens Polygonal Hog House is a historic farm outbuilding in Dewey County, South Dakota. It is located northeast of Eagle Butte, on the east side of South Dakota Highway 63, about 1 mi north of its junction with United States Route 212. It is a 10-side structure, with walls and foundation of concrete and stone, and a conical wood frame roof with low pitch, and is partially set into a sloping hillside. It has a single entrance and four windows. The interior is organized with wedge-shaped pens on the outside of a central open area, from which feed and water can be distributed efficiently to the pens. The structure was built in 1926-28 by August and Frank Laurenz, and was used as a hog house until 1956. It has since seen a variety of other agricultural uses.

The building was listed on the National Register of Historic Places in 1995.
