1. This is Aldie Mill Historic Park! Marker
Discover a part of Northern Virginia's industrial heritage—the restored gristmill at Aldie Mill Historic Park. Built between 1807 and 1809, the Aldie Gristmill was once the largest mill of its kind in Loudoun County.
The mill is operational, making it possible for visitors to watch live demonstrations. The site offers educational activities and events for all ages. Guided tours and demonstrations are available weekends between April and November.
Among the mill's many prominent 19th-century visitors was President James Monroe, who had is grain ground here while living at neighboring Oak Hill.
Aldie Dam
Located about a mile west of this site is the Aldie Dam. Charles Fenton Mercer obtained legal rights to erect this dam in 1804, raising the water level to supply an industrial complex. Wooden gates at the dam allow water from the Little River to flow down the millrace along the length of the town to power the mill's large, tandem waterwheels.
The Mill Complex
The merchant mill and store house—the oldest structures in the present Aldie Mill complex—were built between 1807 and 1809 by William Cooke for the noted legislator and reformer Charles Fenton Mercer. Also preserved at the site are a brick granary erected to the west of the main structure between 1809 and 1816, and a smaller brick country mill that Mercer erected to the east of the merchant mill after purchasing Cooke's half-interest in the enterprise in 1816. During the term of Mercer's proprietorship, Aldie Mill emerged as the largest mill of its kind in Loudoun County.
Tours & Demonstrations
Guided tours of the mill are available April through November, or choose to take a self-guided tour.
