Union Oil Company Building

The Santa Paula Hardware Company Building, located in Santa Paula, California, and more commonly referred to as the Union Oil Company Building, is significant for its historical importance as the birthplace of the Union Oil Company on October 17, 1890. The building continued to serve as a field division office after the main headquarters moved to Los Angeles in 1900.

The building is a California Historical Landmark (#996) and listed on the National Register of Historic Places (NPS-86002619).

California Oil Museum

In 1950, the Union Oil Museum was established and in 1990, for its Centennial Celebration, the building was restored to its original appearance and reopened as a new state-of-the-art oil museum known as the California Oil Museum. The exhibits include oil and gas industry equipment such as an 1890s iron and timber operating drilling rig, historic gas pumps and product containers, a recreated 1890s period Union Oil Company corporate headquarters office and a 1930s period apartment.
