The Lower Mill stood along the Lamington River in what is now Pottersville’s Historic District. The building dated from around 1842 and produced flour till 1915. By the late 20th century, the building was deteriorating and was torn down in 1972. The machinery was saved and used to restore the Cooper Mill in Chester Township. Today, a monument erected by the Morris County Park Commission, which salvaged the parts, marks the location.
