The Bartholomew Park Museum provides fascinating insights into the property’s storied past. Curated displays reveal artifacts from the estate's 150- year spectrum, starting in 1857 when it was recognized as the birthplace of modern viticulture, pioneered by Hungarian nobleman Agoston Haraszthy and ending with the estate's present-day history as a pioneer in organic farming.

The exhibit also includes an extensive display of photos by Victorian photographer Eadweard Muybridge from his “A Vintage in California” series (1870-71) which provides a captivating chronicle of viticultural practices of that time. Paraphernalia and documents, including wall murals and agricultural tools from the last century, are on display.

The museum and winery are open daily from 11 a.m. until 4:30 p.m. Private guided tours can be arranged by calling 707.939.3026.


Bartholomew Park Winery is situated in the heart of the 400-acre Bartholomew Memorial Park in Sonoma. A visit to the winery includes a sampling of Bartholomew Park Winery’s premium wines, access to vineyard-view picnic grounds, hiking trails, and a museum chronicling the property’s illustrious history and current grape growing practices.

The picnic grounds at Bartholomew Park, managed by the Bartholomew Park Foundation, overlook the vineyards and a replica of Agoston Haraszthy’s Palladian Villa which was destroyed by fire at the turn of the century. Groups of 8 or more require permission from Scott Clyde, GM of the Foundation, to use the picnic grounds: 707.938.2244 or

In the hills behind the winery are approximately three miles of marked hiking trails. A variety of indigenous California vegetation -- oak groves, manzanita, madrone, redwood-shaded fern grottos, and fields of spring wildflowers -- provides visitors with a generous sampling of the visual delights and natural beauty of Sonoma County. On a clear day, the view from Bartholomew Park’s trails extends to San Francisco.

The Palladian Villa is maintained by the park and is open Saturdays and Sundays from noon to 3pm.
