Hi Joan I found this mention of Wooded Island you can find the entre article at http://www.state.il.us/hpa/Courthouse.htm Cris <snip> "When the St. Louis Fair ended, the building was again auctioned. Purchased on behalf of the Chicago Historical Society and the Chicago Centennial Commission, in 1905 the timbers were shipped to Chicago's Jackson Park; the courthouse was reconstructed, smaller yet, on Wooded Island. "
