Oatlands Historic District
Also known as: See Also:Oatlands
Why it's listed
Southwest of Leesburg, this 947-acre district in Loudoun County extends the setting of George Carter's Oatlands plantation. Earlier protection covered the main house and about 300 acres; later gifts and easements tripled the area to preserve the open landscape. Three sites are described. Oatland Mills, on Goose Creek, survives as stone and brick fragments and traces of the mill race. A surviving ledger from 1816 to 1825 records Carter's milling and other services, and the mill was destroyed about 1905. Mountain Gap School is a small red one-room building, apparently from the late nineteenth century, and was the last operating one-room school in the county when it closed in 1953. The Church of Our Savior, an Episcopal brick church consecrated in 1878, keeps a gallery above its west entrance. Together they formed a small crossroads community and show how the plantation operated.
Significance in brief: The expansion brings in lands and structures historically tied to Carter's plantation, creating a contiguous and visually integrated landscape. The mill site documents Carter's business operations and a small crossroads community. The school was the last operating one-room school in Loudoun County, and the church reflects the local rural community of the late 1800s.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
