Arcadia Mill was the first and largest water-powered industrial complex in antebellum Florida. It originated in 1817 as part of a Spanish land grant of approximately 680 acres. The site’s ironstone outcropping, a desirable mill seat, a sufficient source of water, and an abundant stand of virgin pine made it well-suited to the lumber industry. Between 1828 and 1855, the Arcadia industrial complex developed into a multi-faceted operation that included a railroad, two water-powered sawmills, a bucket factory, shingle mill, textile mill, and an experimental silk cocoonery. In addition to its industrial facilities, the surrounding Arcadia community was an ethnically diverse settlement, populated by enslaved African-American laborers, Anglo-American workers, and an elite management class. In the late 1980s, efforts by the Santa Rosa Historical Society and the University of West Florida helped save a portion of the site from modern development. Through ongoing archaeological and historical research, many aspects of the site have been investigated, including its dam, first sawmill, textile mill, and the residential areas of the Arcadia settlement.
