Temple Hall
Also known as: Temple Hall Farm Regional Park; VDHR File No. 053-0303
Why it's listed
Temple Hall is a 286-acre farm in the rolling foothills of the Catoctin Mountains in northeastern Loudoun County, Virginia. Its centerpiece is a five-bay, 2½-story Federal-style brick house built around 1810 by William Temple Thomson Mason, set on a small bluff at the end of a tree-lined drive. The house has Flemish bond brickwork, a hipped metal roof, a paneled double door with pilasters and a fanlight, and a 1½-story brick wing to the east. A 1940s renovation by the Symington family added the pedimented portico and steel tie rods to stabilize the building. Nearby stand a brick smokehouse, a converted icehouse, a 19th-century barn and other farm buildings, with open fields around them. The property is significant for architecture and for agriculture. The farm kept working until 1985 and was a leader in crop trends, and the district boundary reflects the farm as it existed from about 1810 through 1956. The property is now a regional park.
Significance in brief: The nomination argues the property is significant under Criterion A for agriculture, as a farm that operated until 1985 and led local crop trends, and under Criterion C for architecture, as a well-preserved Federal-style farmhouse with its outbuildings. The period of significance runs from circa 1810 to 1956.

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).
