California Historical Landmarks Program

Historical Landmarks are sites, buildings, features, or events that are of statewide significance and have anthropological, cultural, military, political, architectural, economic, scientific or technical, religious, experimental, or other value. Historical Landmarks are eligible for registration if they meet at least one of the following criteria:

1) Is the first, last, only, or most significant of its type in the state or within a large geographic region

2) Is associated with an individual or group having a profound influence on the history of California

3) Is a prototype of, or an outstanding example of, a period, style, architectural movement or construction or is one of the more notable works or the best surviving work in a region of a pioneer architect, designer or master builder.

California’s Landmark Program began in the late 1800s with the formation of the Landmarks Club and the California Historical Landmarks League. In 1931, the program became official when legislation charged the Department of Natural Resources—and later the California State Chamber of Commerce—with registering and marking buildings of historical interest or landmarks. The Chamber of Commerce then created a committee of prestigious historians, including DeWitt Hutchings and Lawrence Hill, to evaluate potential landmark sites.

In 1948, Governor Earl Warren created the California Historical Landmarks Advisory Committee to increase the integrity and credibility of the program. Finally, this committee was changed to the California Historical Resources Commission in 1974. Information about registered landmarks numbered 770 onward is kept in the California Register of Historical Resources authoritative guide. Landmarks numbered 669 and below were registered prior to establishing specific standards, and may be added to the California Register when criteria for evaluating the properties are adopted.

Amador County and wineries have shared a common past since the days of the Gold Rush. The D’Agostini Winery in Plymouth is one of the oldest in California. The winery was started in 1856 by Swiss immigrant, Adam Uhlinger. Some of the original vines are still in production. In 1911, Enrich D’Agostini purchased the winery and its 125 acres of vineyard. Today D’Agostini Winery is owned by the Sobon Estate Winery and is distinguished by being the longest running producer of Zinfandel Wines. The winery also produces Rhone varietals and dessert wines.

The original wine cellar, with walls made from rock quarried from nearby hills, hand-hewn beams and oak casks standing as part of the Shenandoah Valley Museum at the D’Agostini Winery location of the Sobon Estate winery. The museum is located in one of the original D’Agostini Winery buildings to display a collection of artifacts that tell the story of the beginnings of the area’s wine region.

As a combined result of prohibition and decline in area population, only a few wineries survived. Today with an ideal climate for wine-making, The Shenandoah Valley of Amador County represents an important region for California wines. Dozens of wineries dot the landscape of Amador and neighboring counties. Many wineries are family owned and invite guests in for wine tastings, picnics (bring your own or purchase takeout) and stores with wine related gift items.

The historical landmark is located on Plymouth-Shenandoah Road 7.2 miles northeast of Plymouth on the grounds of the Sobon Estate Winery.

Amador County

Amador County was one of the most productive of the “Mother Lode” counties. The mine shafts were reported to be among the deepest in the world. Mining continues in select areas today. The eastern slope of Amador County begins at Kirkwood’s historic stage stop. The relatively narrow county is aligned between the Mokelumne and Cosumnes rivers and roughly follows an important emigrant trail route. Gold rush camps and boom-towns abound in the history of the area. Amador County is also recognized for its dozens of vineyards and wineries.
