Walnut Hill Cotton Gin
Approximate location: the National Park Service places this pin arbitrarily within the property, not at a surveyed point (stated accuracy ±12 m).
Why it's listed
Set alone in rural eastern Wake County, this cotton gin house was probably built in the mid to late 1840s by planter and commission merchant Alonzo T. Mial. The frame building rests on tall, dressed granite piers, and its three floors were arranged for each stage of ginning. A mule-powered drive room, gins, a press and storage areas sat under one roof. Inside survive five nineteenth-century gins, feeders, a condenser, a Munger suction system, and an early twentieth-century double-box press. Two 1920s-patent gins replaced the older stands. Outside are a steam engine and a small shed roofed with 1933 license plates. Mial and later his son Millard operated the gin, which also processed cotton for neighboring farms, until the mid 1930s. The property is considered significant because few antebellum gin houses remain in North Carolina, and this one keeps equipment from its entire working life. Buried features, including the wagon scale pit, may add further information.
Significance in brief: The nomination argues it is one of a handful of intact antebellum gin houses surviving in North Carolina. It also keeps a significant collection of ginning equipment covering its whole operating life, from the late 1840s to the mid 1930s. It is tied to planter Alonzo T. Mial and his son Millard, and has potential archaeological remains, such as the wagon scale pit.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved. See what listing means in practice.
