Pena Adobe Historical Society

The Peña Adobe Historical Society was established in 2004, staffed by volunteers, this nonprofit organization is committed to preserving the Adobe and providing interpretive programs for the community.

Some of the first settlers to arrive in Solano County were the families of Juan Manuel Vaca and Juan Felipe Peña.  The Vacas and Peñas traveled from the New Mexico region to California following the Old Spanish Trail in 1841. The oldest structure built in Solano County, the Peña Adobe and the former home of the Peña family, was built in 1842.  While the Vaca Adobe no longer stands, the Peña Adobe is listed on the National Register of Historic Places and California Historic Landmark #534.

The Peña Adobe Historical Society opens the Adobe and adjacent Museum providing tours, school field trips, summer camp and events to share Vacaville's rich heritage!
