Oklahoma State Capitol Oklahoma's first capital was Guthrie, Oklahoma, but it moved to Oklahoma City in 1910. Construction began on the Oklahoma State Capitol in 1914 and was completed in 1917. Originally, it housed the judicial branch of Oklahoma, but the state's high courts moved most of their operations to the Oklahoma Judicial Center in 2011, leaving only the Supreme Court Hearing Chamber in the capitol building.
