Pena Adobe Historical Society
Making California history come alive!
Located on Peña Adobe Road off Interstate 80 is Peña Adobe Park. The center of attraction at the 1½ acre historical park is the oldest structure built in Solano County, the Peña Adobe, California historical landmark #534 and the former home of the Peña family.
The Peña Adobe was erected in 1842. The simple adobe with its dirt floors and four windows still has the original hand-hewn redwood timbers which were cut in the hills near Napa. The walls are two feet thick and made of 23”x10”x3” adobe mud bricks. 25 Mission-trained Indians sun dried the adobe bricks and built both Vaca and Peña’s adobes. (The Vaca Adobe was built to the east of the Peña Adobe. It was destroyed by the earthquake of 1892.)
The Peña Adobe Historical Society was established in 2004, staffed by volunteers, this nonprofit organization is committed to preserving the Adobe. The park now includes the Mowers-Goheen Museum, the Willis Linn Jepson Memorial Garden, Indian Council Ground and picnic and recreation facilities.
Today this gateway to Vacaville is open the first Saturday of the month February thru December and private tours upon request with interpretive programs provided by the Peña Adobe Historical Society.
Explore Vacaville’s rich history through art, architecture, and adventure. From a deep dive into history at one of the oldest structures in the county to a trip down memory lane riding hobbyhorses and trains at the Nut Tree, you’ll discover a city brimming with fun historic anecdotes and antiquated beauty just waiting to be discovered!
