DelaplaneHistoric District is a national historic district located at Delaplane, Fauquier County, Virginia. The rural village of Delaplane was founded in 1852 around the Piedmont Station of the newly chartered Manassas Gap Railroad. The railroad built a station, a warehouse and a store, and a town grew, as with the adjacent stops at Marshall and The Plains. As Delaplane prospered, the previously prosperous town of Paris on the Dumfries-Winchester Road, lagged. The town's name was changed in 1874 to honor its postmaster and owner of the general store, Washington E. Delapane. The historic district today looks much like in 1861, when troops embarked en route to the First Battle of Bull Run, although that conflict devastated the area. The surrounding area is part of the Commonwealth of Virginia's Mosby Heritage area, the first such heritage area and designated in order to draw attention to the historic, natural and cultural resources in this section of Northern Virginia. It was listed on the National Register of Historic Places in 2004. It is included in the larger Crooked Run Valley Rural Historic District also designated that year. It includes 24 contributing buildings and 3 contributing sites in Delaplane. Several residential and commercial buildings date from the mid-19th century; other dwellings and business date from the late-19th- and ear1y-20th century dwellings and some commercial structures. Notable buildings include two vernacular Greek Revival style, two-story, brick structures that were used as stores, stations, and warehouses ; Roger's Depot; the Delaplane House ; the old Shacklett's Mill ; the old Delaplane Store that now houses the post office; and the McDonald House. The Westminster Presbyterian Church lies in this historic district, but the current town's two historic churches both lie slightly outside the limits of this historic district, although within the Crooked Run Valley historic district: Emmanuel Episcopal Church and Pleasant ValeBaptist Church.
