The Gamble Sugar Mill ruins are part of a 16 acre Florida State Park system site known as the Gamble Mansion or Gamble Plantation, located in Ellenton, Florida. The mill ruins (c. 1845) are part of a plantation landscape that include an Antebellum mansion and extant tabby cisterns and other building features. Historically, the plantation was more than 3,500 acres in size, and more than 200 slaves were used to work the property and for the processing of sugarcane at the mill site.
