This 97-acre working farm in Maryland, which traces its roots to the 17th century, is heading to auction on April 9.

Known as P.A. Bowen Farmstead, the Brandywine farm includes a 19th-century home with a kitchen that, in part, dates to 1665 — before the United States was an independent nation.

Located at 15701 and 15407 Doctor Bowen Road — just an hour outside Washington, DC — it was last asking $7.5 million for sale.

The no-reserve auction was first reported in Mansion Global.

The seller is Sally Fallon Morell, who built the farm with her late husband, Geoffrey Morell.

“Raising a dairy herd and making cheese the old way — chemical-free, with the land doing what land is meant to do — was a dream Geoffrey and I built together over 15 years, and I’m proud of every bit of it,” Morell told Gimme Shelter, adding that continuing to work after losing her husband was both a “tribute and a comfort.”

However, she added: “The time has come to pass this farm to someone who will love it as we did.”

Morell is the co-author of “Nourishing Traditions,” which promotes a diet that incorporates raw milk and saturated fat, contradicting low-fat heart health guidelines. She is also co-founder of the Weston A. Price Foundation, a nonprofit that advocates for raw milk to be available for consumption in all 50 states and argues that a diet high in animal fat, like butter, lard and tallow, is good for you. (Price was a dentist who traveled the world in the 1930s and believed that people who ate like their ancestors, including a diet with no processed sugar or white flour, had better teeth and health than his patients.)

The estate includes an 1870s Italianate-style home. Elite Auctions is handling the sale of the property, which is listed by Bob Lucido and Tracy Lucido of Keller Williams Lucido Agency.

The 5,500-square-foot, six-bedroom, 6.5-bath home comes with 13-foot ceilings, crown moldings, hardwood floors and seven fireplaces. Outside, there’s a pool and a pond with a dock.
