CHICAGO (WBBM NEWSRADIO) -- An 1850s-era Joliet mansion that was headed for the wrecking ball more than a year ago, instead, is being rolled to a new location on Monday. The Casseday Mansion was finished being built around 1851, but preservationist Mary Beth Gannon said the first and smaller portion of the now-two-story limestone building was built in the 1830s.
