Commissioned in 1855 by central Illinois businessman and politician, William Reddick, the splendid mansion was the home of the Reddick family for nearly 30 years. The twenty-two room mansion was designed for the William Reddick family by two prominent mid-western architects: William B. Olmsted and Peter A. Nicholson.
The fifty foot high Reddick Mansion was built with four floors and an attic. The elaborate style on the exterior is also seen in the interior, particularly on the second and third floors.
