Also known as: Mather Mill

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
Farmar's Mill is a three-story grist mill of dressed fieldstone with a gabled roof that extends below the second-story windows, standing beside the Wissahickon Creek in Fort Washington, Montgomery County. It was built on land within a 5000-acre tract purchased from William Penn in 1683 by Jasper Farmar, a British Army major who died before emigrating. His widow Mary and son Edward inherited the acreage, and the family arrived in Philadelphia in 1685. Farmar built the stone mill between 1685 and 1700, and it operated for roughly two centuries. The mill is significant for its early construction, its long working life, and its association with Farmar, who became an interpreter at Peace Councils held with local Indians. The building has been enlarged since it was first constructed and remains on its original site.
Significance in brief: The nomination argues the mill is significant as an early stone grist mill associated with Jasper Farmar, an early settler of the Whitemarsh area, who is said to have served as an interpreter at Peace Councils held with local Indians. The mill is described as having remained in operation for approximately 200 years.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
