The so-called Addison blockhouse, situated on the old Addison grant near the Tomoka River in coastal Volusia County, has long been an enigma. The alternatives of dating suggested by persons interested in it have ranged from the sixteenth to the nineteenth century, and its builders have variously been claimed to have been Spaniards, Englishmen, or Americans. In order to lay plans for a valid interpretation of the structure to the public, the Florida Park Service undertook a study to determine its origin and history.
