Long Pond Iron Works

The Long Pond Ironworks, located in present-day Ringwood, New Jersey, was established in 1766 by German ironmaster Peter Hasenclever of the London-based American Company. Situated near rich deposits of iron ore, vast forests for charcoal, and waterways for power and transport, the site quickly developed into a major ironworking community. The operation included a blast furnace, forge, water-powered bellows, and worker housing, and it played a vital role in regional industry throughout the 18th and 19th centuries.

During the American Revolutionary War, the Long Pond Ironworks contributed significantly to the war effort by producing cannonballs, iron fittings, and other essential materials for the Continental Army. The site remained in operation through various ownerships into the late 19th century, adapting to changing technologies and demands. Today, the Long Pond Ironworks Historic District is preserved within Long Pond Ironworks State Park, where ruins of the furnace, waterwheels, and workers' village can still be seen, offering a rare glimpse into early American industrial history.
