Stonemasons Joe E. Bishop, "Rocky" Davis, and "Old Frank" Hamilton built this 2-story native stone mill for William T. Miller (1846-1936) in 1882. Steam power was used to grind grain here until a crude oil engine was installed (1918). The grist mill was converted to feed production after W. M. Wright and his son-in-law, Ted C. Robbins, purchased it in 1926. In 1974 Robbins and his wife gave the structure to the Dublin Historical Society as a museum for W. M. Wright Historical Park. Recorded Texas Historic Landmark - 1975
