Listed on the National Register of Historic Places since 1979, this remarkably preserved 10-building industrial complex dates to the early 1700s and features a stone gristmill (rebuilt 1877), sawmill, linseed oil mill, grain silo, and associated buildings, art galleries and cultural events, educational programs about early American industry, scenic Delaware River and D&R Canal setting, and management by the Delaware River Mill Society.

Industrial Heritage

Milling activity at this site dates to the early 1700s. John Prall Jr. purchased the property in the 1790s and expanded the original gristmill into a multi-building industrial complex including a sawmill, linseed oil mill, and stone quarry. The current stone gristmill was rebuilt in 1877 on the foundations of an earlier mill that burned in 1874. The complex operated continuously until the 1950s, when it fell into disrepair. Local residents Donald and Beverley Jones purchased the property to save it from development, and the State of New Jersey acquired it in 1973.

Cultural Center

Today, the Delaware River Mill Society manages Prallsville Mills as a cultural and community resource. The restored buildings host art galleries, exhibitions, concerts, festivals, and educational programs. The scenic setting along the Delaware River and the D&R Canal makes it a popular destination for history enthusiasts, artists, and visitors exploring the river towns of Hunterdon County.
