While Illinois boasts some grand structures like the Lincoln Home (1839), the undisputed champion of age lies beneath your feet – the Cahokia Mounds State Historic Site. However, the title of “oldest building” goes to a fascinating structure within the site: the Old Cahokia Courthouse Built around 1737-1740, this vertical log cabin served as a private home during French colonial Illinois.  Later acquired by the U.S. government, it flourished as a courthouse and political center in the 1790s. In a twist of fate, the building was totally dismantled and displayed at world’s fairs before being reconstructed on its original site.
