HOLD: In 1921, Beatrix Farrand, a founding member of the American Society of Landscape Architects, designed the garden for Dr. Frederick Peterson, a noted New York neurologist who entertained family, friends and clients on the 300-acre property, which is situated at the confluence of the Shepaug and Housatonic rivers.

HOLD: Officials said that by the time its present owner, the non-profit Promisek group, acquired the property in 1978, all traces of the garden had been buried under years of overgrowth.

HOLD: In 1992, Roxbury resident and garden historian Pamela Edwards rediscovered the historic value of the walled garden, and a restoration began using the plan found in the Farrand archives at the University of California at Berkeley.

Promisek at Three Rivers Farm is located at 694 Skyline Ridge Road.
