Mill Drawing by Kathy Koebel

Incorporated as a city in 1986, Byrnes Mill traces its roots back to the 1800s with the building of the Mill on the Big River. The city of Byrnes Mill grew up around the Mill on the Big River. Now home to about 3,000 citizens, Byrnes Mill is known for its parks and pleasant residential areas.

Original Mill
The original mill was replaced in the 1880s by the structure depicted in this drawing by Kathy Koebel on the cover of the Fall, 1988 edition of "Reflections."

Unfortunately the Mill itself is gone but visitors can see the mill site on the Big River in the Byrnes Mill City Park.  Visit our City Park Page HERE.
