Bulow Plantation Ruins Historic State Park is a Florida State Park in Flagler Beach, Florida. It is three miles west of Flagler Beach on CR 2001, south of SR 100, and contains the ruins of an ante-bellum plantation and its sugar mill, built of coquina, a fossiliferous sedimentary rock composed of shells. It was the largest plantation in East Florida, and was operated with the forced labor of enslaved Africans and African Americans.
