“Pleasanton’s Alviso Adobe Community Park is a unique site that tells the story of California from its earliest human history. This fully restored interpretative park reveals the history of the Amador Valley, offering a rare glimpse of times past – from its Native American beginnings to the days of Spanish Ranchos managing herds of cattle on the original 12,000 acre Rancho Santa Rita, through a period in the early to mid-20th century when it was a popular dairy and finally its present as a community park.”
