Adelphi Mill

Adelphi Mill is a two-story water-powered structure built from fieldstone and pine with original grinding wheels and mechanical systems inside. The building preserves 18th-century technical installations that show how water provided energy for grain milling operations.

The milling structure was built in 1796 by the Scholfield brothers as a working production center for the region. During the 19th century it came under the control of George Washington Riggs and became part of his larger estate, giving the place new importance.

The mill demonstrates how industrial production worked in this area and what role water-powered mills played in people's daily lives. Visitors can see how grain was processed and understand why such places mattered to the community of that era.

The grounds include parking areas, picnic spots, and playground equipment, making it a good destination for family visits. The location on Riggs Road is easy to find, with ample space to rest between exploring the building.

The building is the last surviving historic mill structure in the entire county and offers a rare opportunity to see the machinery of this era still in place. Its size and completeness make it an especially important example of early American manufacturing.
