We can drive down to see it though. "The Cahokia Courthouse was originally built as a French dwelling around 1740. In 1793 it became a courthouse, and for 20 years it served as a center of political activity in the Old Northwest Territory. "From December 1803 until the spring of 1804, Lewis and Clark used the courthouse as a headquarters. From there they collected information, met with territorial leaders, gathered supplies and corresponded with President Thomas Jefferson. During that time the Corps of Discovery camped at nearby Camp River Dubois. "The courthouse, initially built as a dwelling in the 1730s, is a unique remnant of the French presence in Illinois. Converted to a courthouse in 1793, for the next 20 years it served as a center of political activity in the Northwest Territory. It was dismantled in 1901, re-erected twice, and reconstructed on its original site in 1939. The structure is an excellent example of early French log construction known as poteaux-sur-solle. Upright hewn logs are seated on a horizontal log sill; the spaces between logs are filled with stone and mortar chinking. The building rests on its original stone foundation and contains four rooms that originally functioned as a courtroom, a schoolroom, and legal offices." from https://www.nps.gov/places/old-cahokia-courthouse.htm
