About
Aldie Mill Historic Park offers a unique journey into Virginia's industrial past. This beautifully preserved 19th-century gristmill stands as one of the best-outfitted early mills in Virginia, renowned for its rare operational tandem overshot waterwheels. Nestled along the scenic Little River, the district invites visitors to explore a crucial piece of Loudoun County's heritage and experience a bygone era where waterpower fueled daily life.
The centerpiece of the district is the four-story Aldie Mill, where visitors can witness live grinding demonstrations powered by its impressive twin metal waterwheels. Beyond the mill itself, the historic district includes a brick granary dating from 1809–1816, the miller's house, and the Federal-style Mercer House, offering a comprehensive glimpse into the complex that once served as the largest factory of its kind in Loudoun County. The intricate original machinery inside the mill provides a fascinating look at early 19th-century technology.
Visiting Aldie Mill Historic Park is an immersive experience that transports you back in time, offering educational insights into manufacturing history, the impact of the Civil War, and even connections to President James Monroe. Its blend of historical significance, architectural charm, and picturesque natural surroundings along the Little River makes it a memorable destination for history buffs, families, and photographers alike, showcasing the enduring legacy of an essential community hub.

The Aldie Mill has a rich history dating back to the early 19th century. Charles F. Mercer, a lawyer and legislator, obtained the rights to dam the Little River in 1804 and subsequently built the mill between 1807 and 1809 with William Cooke. Mercer named the growing village Aldie after his supposed ancestral home, Aldie Castle in Scotland. The mill quickly became a vital economic center, grinding wheat and corn for markets along the East Coast and in Europe, and for a period, it was the largest gristmill in Loudoun County. The mill was sold to John Moore in 1835, and his descendants operated it for six generations until its closure in 1971. During the Civil War, the mill played a role in the conflict, providing grain for both Union and Confederate troops and witnessing incidents such as John Singleton Mosby's capture of Union soldiers in what became known as "the Aldie Races." The site was acquired by NOVA Parks in 2006 from the Virginia Outdoors Foundation and underwent extensive restoration, including its twin overshot waterwheels, which were restored in 2010.
