The Old Washington County Courthouse was the courthouse for Washington County, Utah from its completion in 1876 to 1960. Located in St. George, Utah, the courthouse is a two-story red brick structure with unusually thick walls. The 36.33ft by 40.33ft structure rests on a high basalt rock foundation that comprises the ground floor, and is capped by a pyramidal hipped roof with a prominent wood cupola.The courthouse was listed on the National Register of Historic Places on September 22, 1970. The building is used for Chamber of Commerce offices and storage. The third-floor courtroom is used for lectures. The building may have been designed by William H. Folsom, who designed the similar but larger Salt Lake City Council Hall.
