Established in 1852, the Old Almaden Winery was the oldest winery in California,^[2] and the site is designated as a California Historical Landmark.^[1]

The winery is no longer in operation - the Almaden Vineyards company moved to Madera, California, and the vestigial remains of the property have been made into a public park. Much of the prior winery grounds have also been converted to single family homes, following a series of environmental planning studies.^[3][4]
