Built around 1890, the Rodman Octagonal Barn near Edgeley is one of the earliest examples of this type of agricultural architecture. Luman B. Rodman was an early settler of the state, arriving from New York in 1882. His barn was built using the octagonal shape and heavy dimension lumber of the time. The structure was entered into the National Register of Historic Places 1986-08-21 as part of a Round Barn Thematic Nomination.
