The old Logan County Courthouse, c. 1840 was relocated to Greenfield Village (historical park) in Dearborn, Michigan (a suburb of Detroit). The sign in front of the building reads "Logan County Courthouse - Postville, Illinois, served as the Logan County seat from 1839 to 1847. Residents won that designation by promising to build this courthouse, completed in 1840. A young lawyer and prominent Whig politician named Abraham Lincoln argued cases here while traveling the Eighth Judicial Circuit."...."From Postville, now Lincoln, Illinois." Greenfield Village, built by Henry Ford, is a very interesting place to visit. Many famous historical building and artifacts from around the country have been brought here and restored. Robert P.
