The California Oil Museum at 1001 E. Main Street, Santa Paula (corner of Main and 10th) is the birthplace of Union Oil Company (aka Unocal and more recently acquired by Chevron in 2005).

The building was completed on October 17, 1890. at the Santa Paula Hardware Company Building, with the Union Oil Company offices upstairs. The company’s main headquarters moved to Los Angeles in 1900, but the building continued to serve as a field division office.

The Union Oil Museum was established in 1950. In 1990, the building was restored to its original appearance for its centennial celebration. Click here for an early picture of the building. The building is also a California Historical Landmark and is listed on the National Register of Historic Places.
