a 5.5-magnitude earthquake near El Reno caused several cracks to materialize in walls and ceilings of the Capitol, including one crack measuring about 50 feet in length. Expansion and change (1998–present) In 1998, state legislators and the governor enacted legislation to create the Oklahoma Centennial Act, which formed the Oklahoma Capitol Complex and Centennial Commemoration Commission. The commission worked to fund a dome, which was in the initial plans in 1914, for the Oklahoma State Capitol and construction of the dome began in 2001 and was completed in 2002. It included a bronze sculpture called The Guardian. During exterior restoration work in 2014, engineers discovered significant cracks in the precast panels that comprise the dome, but not in any of the supports, contrary to what some think. The building was designed and built to support the dome. When the Layton and Smith firm (the firm selected to design the building) presented its preliminary drawings to the commission in 1914, the plans did not include a dome. However, the building was designed to allow for a weighty dome to adorn the central square rotunda. The original commission was split on the desirability of the dome due to the high cost, and as completed, the capitol was not domed In 2006, plans were made to move the judicial branch into the old Oklahoma Historical Society building, as the agency was moving into the Oklahoma History Center. The court offices moved to the new Oklahoma Judicial Center in 2011. Ten Commandments Monument controversy Exterior and Capitol complex The Oklahoma State Capitol, located at 2300 North Lincoln Boulevard, Oklahoma City is composed primarily of white limestone and Oklahoma pink granite. However, the building's dome is made of steel-reinforced concrete and reinforced plaster casts. The state capitol complex is famous for its oil wells and remains the only state capitol grounds in the United States with active oil rigs. The capitol building is directly atop the Oklahoma City Oil Field. The state capitol building and the surrounding government buildings, non-government agencies, museums, libraries, and tree lined streets and boulevards form the Oklahoma State Capitol Complex or Capitol Campus. The complex includes the State Capitol Park, the Oklahoma History Center, the Oklahoma Judicial Center, and the Oklahoma Governor's Mansion. The mansion has a limestone exterior to complement the Oklahoma State Capitol's exterior. The surrounding neighborhood is home to numerous restaurants and bars. The Oklahoma History Center
