Originally built in 1926 by E.E. Benjamin, the flour mill that produced Arva-Pride flour at 5590 Olde Wadsworth Boulevard operated until 1944 when the demand for the milling industry shifted towards larger scale concrete silos along highways. As a result, the property was sold to the Tiller and Schaaf families. The mill was listed on the Register of Historic Places in 1975, followed by the Arvada Historical Society performing a major renovation. Subsequently, it was opened as a museum to the public. In 1998, the Arvada Urban Renewal Authority purchased the mill property and donated it to the City of Arvada for lease to the Arvada Historical Society.
