Illinois State Capitol ~ Springfield Illinois ~ Historic Building
The current capitol is in the architectural style of the French Renaissance. The capitol was designed by Cochrane and Garnsey, an architecture and design firm based in Chicago, Illinois. Ground was first broken for the new capitol on March 11, 1869, and it was completed twenty years later for a total cost of$4,500,000.
The capitol dome is covered in zinc to provide a silver 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).
