Rockport is rooted in a small settlement known as Benton's Ferry, which developed along the Green River in the early 19th century. When a post office was established in 1863, the settlement used the name "Rock Port" (later shortened to a single word). Originally located primarily along the river, most of the city has since shifted to the bluff above the river.[2]
