Travel back in time to Milltown, a thriving community situated along the Black River. Built in 1826, Cooper Gristmill was once the heart of a thriving industrial community and played a vital role in the area's development during the Industrial Revolution. The Gristmill is the only restored water-powered mill in New Jersey and is listed on the State and National Registers of Historic Places. Witness the amazing power of the Black River, harnessed to run a steel water wheel and grind grains into flour using massive 2,000-pound millstones. These grinding stones can produce up to 800 pounds of flour per hour. Visitors are invited to take home stone-ground flour and cornmeal produced at the Gristmill.
WHAT TO SEE AND DO
- Learn about the social, agricultural, and technological aspects of life in the nineteenth and early twentieth centuries
- Embark on a guided tour of the Gristmill led by period-clothed staff
