Home to all three branches of state government and vast collections of priceless state art, the State Capitol is itself a work of art, and is more uniquely Oklahoman than any other Oklahoma building. It was Oklahoma’s grandest achievement as a young state when it was built between 1914 and 1917. But in 2014, after a century of heavy use, harsh Oklahoma weather and inconsistent maintenance and preservation efforts, the building’s mechanical systems were failing, the exterior façade was crumbling and its prospects of meeting the state’s needs for another hundred years were fading. Recognizing the need to act, the Legislature and Gov. Mary Fallin in 2014 enacted legislation providing funding to begin the Capitol’s first-ever comprehensive, top-to-bottom restoration. Exterior work begins in 2015 followed by interior work in 2016.
