The IOOF Building is in its original location in The Plaza. It has an eclectic architectural style common in small western towns during the middle to late 19th century. Locally designed,it was built of local clay brick by local bricklayers.
It was funded by merchants and Oddfellows. Until 1978, when the Ashland IOOF Lodge joined with the Jacksonville IOOF Lodge, the building was in continual use by the Oddfellows.

The Independent Order of Odd Fellows (I.O.O.F.) is an altruistic fraternal organization derived from the similar English Oddfellows service organizations which came into being during the 1700s....Although in Britain the Odd Fellows tended to meet in pubs, in the U.S. the lodges often built their own facilities. Many of these are now on the U.S. National Register of Historic Places....
