Located on Old State Highway 12 in Zillah, Washington, the Teapot Dome Service Station was built in 1922. A circular frame building with conical roof, sheet-metal "handle," and concrete "spout," it is an example of the roadside architectural follies built during the expansion of the national highway system in the 1920s and 1930s.

Selling oil products from a teapot-shaped structure was intended as a humorous reminder of the Teapot Dome scandals that rocked President Warren G. Harding's administration (1921-1923). That controversy sent U.S. Secretary of the Interior Albert Fall to prison for leasing government oil reserves in Teapot Dome, Wyoming, and Elk Hills, California, to private producers. The Teapot Dome station continues to operate as a full service gas station and is a familiar sight to travelers in eastern Washington.
