Windom Mill Farm
Also known as: 071-35-0015
Why it's listed
Limestone buildings on a 106-acre working farm beside Blue Rock Road west of Millersville make up this Lancaster County complex, centred on a farmhouse, a stone mill, a tavern, a miller's house and a bank barn. The land was patented to Samuel Herr in 1769, and in 1810 his son-in-law Jacob Kauffman is recorded as having had the large stone flour and feed mill built, with the tavern built at about the same time as a stop for Conestoga wagons on the road to the Susquehanna River. The farmhouse is dated by tradition to about 1780 but is judged stylistically closer to the Federal period, with a five-bay plan, nine-over-six windows and a corner cupboard. The mill and tavern are listed as among the best-preserved examples of their types. The complex is regarded as representative of the mixed Germanic and English vernacular that developed in rural Lancaster County in the late eighteenth century, and of the farming economy the county depended on for more than a century.
Significance in brief: The nomination argues the farm illustrates farming, milling, commerce and tobacco curing important to Lancaster County agriculture from the settlement period onward. Its buildings are presented as typical of the restrained rural vernacular that mixed Germanic and English styles in the late eighteenth century, and the complex is said to have evolved from a farm to a mill and small crossroads community with a post office.

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).
