Monticello in Lewis County, Missouri — The American Midwest (Upper Plains)
Lewis County, Missouri
1832-1982
In December 1832, the legislature passed a bill introduced by the Honorable Charles Allen to organize Lewis County, until then a part of Marion County. The name was chosen to honor Meriwether Lewis, who with William Clark, led the expedition to Oregon in 1804-1806.
The town of Monticello was platted in the Fall of 1833 on 60 acres of ground donated to Lewis County by Andrew P. Williams. After two courthouses were destroyed by fire, the present courthouse was built in 1875 at a cost of $9,750.00 by contractors McAlister and Barnes. Since that time, county and higher courts have been held here.
