Hampton Historical Society, Illinois

Long before Illiniwek Forest Preserve became a place for camping, overlooks, and community gatherings, the old Grist Mill stood along the Mississippi River as part of the region’s working landscape. Connected with the early development of Rapids City and remembered through the name of Alfred Addison Adams, the mill helped transform local grain into flour and meal at a time when farming, river access, and neighborhood industry were deeply tied together. Its massive millstones were tools of daily labor, but they also became symbols of the confidence early settlers placed in the riverfront land and the communities growing around it.

After its original milling days ended, the building was purchased for $100 and moved to Albert Oltman’s farm. The old mill was hauled by barge from its original site to the Oltman property, with the structure supported and drawn in sections, rather than dismantled entirely. There, on the 174-acre Oltman tract stretching along the Mississippi shoreline, the building was reconstructed and served as a barn. In 1944, Rock Island County Forest Preserve Commissioners purchased the Oltman tract from Albert Oltman for $40,000; the land began its transformation from private farm property into public preserve.

In 1976, the barn was destroyed by fire, ending over a century of existence. The tragic loss was more than the disappearance of a weathered building; it was the loss of a rare survivor that connected Hampton to its agricultural and industrial past. The structure had watched the land change from mill site to farm tract to public preserve, and it had served as a backdrop for community life, including the Rock Island County Fair celebrations held at Illiniwek in the early 1950s.

Today, visitors can still find the surviving millstones and foundation preserved as a monument at Illiniwek Forest Preserve. Though the building itself is gone, the monument directs us back to the Grist Mill’s lasting importance—as a place of work, memory, tragedy, and community identity. (Click here for more information)
