The Jacob D. Goosen Barn is a historic barn in rural Sully County, South Dakota about 1/2 mile east of Onida on the north side of East Onida Road. Built in 1904, it was built with a Shawver truss roof, a form popular in other areas, but not widely adopted in South Dakota. This truss method used lighter-weight framing, which transferred the roof's dead load to the walls, enabling the removal of interior posts. The barn is wide and long, with a high gambrel roof that characterizes the use of the Shawver truss. Read more on Wikipedia
