“Hail Twin Falls County” read the headline in the Feb. 15, 1907, edition of the Twin Falls Times. The state legislature had divided Cassia County, creating a new county from the Owyhee County line to Milner. Construction of the Twin Falls County Courthouse began in 1908 and was completed in June 1911, at a cost of $150,000 – equal to more than $3 million in today’s money. The courthouse was built in Classical variants style, and was designed by C. Harvey Smith. The exterior walls were built with Bedford stone and brick. When built, the courthouse was the tallest building in the Magic Valley. The courthouse was the first building in the county to have an elevator. The fourth floor — which has no windows — housed the county jail for decades. The courthouse, which sits across Shoshone Street from the City Park, was dedicated on Oct. 18, 1911, by Idaho Governor James H. Hawley. “No county seat in Idaho has such a structure as this one,” Hawley said.
