The Aldie ZIP Code 20105 has currently the highest median sales prices for houses sold in Loudoun County.

By 1809 the Little River Turnpike was completed from Alexandria to the Mercer Mill, replacing the older rutted section of Belhaven Road.

During the Civil War, the village itself and lands immediately to the west and northwest were the site of the Battle of Aldie during the Gettysburg Campaign.

In addition, the Confederate partisan John Singleton Mosby was active in the village, and several small skirmishes between Union cavalry and his band of rangers took place in and around Aldie.
