The State Capitol Building in Springfield, Illinois. The capitol is in the French Renaissance architectural style and was designed by Cochrane and Garnsey of Chicago. Ground was first broken for the structure in 1869 and it was completed in 1889. The dome is covered in zinc to provide a silvery facade which does not weather. The interior of the dome features a plaster frieze painted to resemble bronze, which illustrates scenes from Illinois history, and stained glass windows (including a stained glass replica of the state seal in the oculus of the dome). With a total height of 361 ft (110 m), the Illinois capitol is the tallest non-skyscraper capitol in the United States, even exceeding the height of the United States Capitol in Washington, D.C.. The only taller state capitols are the non-classical designs of Florida, Louisiana and Nebraska, whose governments opted for modern structures.
