The Alviso Adobe Community Park is a park in the city of Pleasanton, California, United States. It is built around an adobe house constructed in 1854 by Francisco Alviso on the Rancho Santa Rita Mexican Land Grant. The Alviso Adobe is a rare surviving example of an early American adobe that was continuously in use until 1969. The building is registered as California Historical Landmark #510 in 1954, but most of the historical marker was later found to be erroneous. Read more on Wikipedia
