Two miles north of Plainfield to the west of US 218 is an early example of an octagonal barn (1887). This barn has walls of horizontal shiplap boards and a roof that is shingled. Soike speculates that there was probably either a cupola or a windmill at the apex of the roof.
19The interior is divided into the usual two levels, the upper floor used to store hay. A large door gives entrance to the main level; above is a door leading to the hayloft.
