Alviso Adobe

Built in 1854, the Alviso Adobe is one of the few adobe structures remaining in the Bay Area. Declared a California Historic Landmark in 1954, the building stands relatively unmodified since the 1920s. The adobe was in continuous use from 1854 until the Meadowlark Dairy closed in 1969. During the dairy period, workers took their meals in the kitchen and dining room of this building.

OHP description:

This building, erected in 1844-46 by Francisco Solano Alviso, was the first adobe house to be built in the Pleasanton Valley. It was originally called Alisal-The Sycamores. Following the Battle of Sunol Canyon, General John C. Fremont withdrew to this building, which became his headquarters for several days

(note: The part about Fremont staying here may not be true, thus the removal of the plaque.  Thanks to the Delja's for this information.)
