A Rare 80-Acre Sonoma Estate with Historic Farmhouse and Vineyard Behind the Gates of Bartholomew Park. Just minutes above the Sonoma Plaza, this one-of-a-kind 80-acre property offers the space, privacy, and character Bay Area buyers look for in a weekend retreat or long-term legacy home. At its center is a 5-bedroom, 2-bath farmhouse rich with original charm. Antique windows reclaimed from early 1900s San Francisco bring in natural light and nod to the home’s history, while a screened-in front porch sets the tone for relaxed indoor/outdoor living. The land blends vineyard blocks with wide-open acreage, creating both beauty and potential. A large pool and pool house offer a resort-style escape, and a classic car barn with a guest studio above provides space for visitors, hobbies, or a private office. The views are incredible, hills, vines, and open sky in every direction. Properties with this kind of scale, warmth, and proximity to town rarely hit the market.
